Information About Cisco AS5850 Universal Gateway Commissioning

To build a network using the Cisco AS5850, it is necessary to understand the following:

•The route-switch-controller (RSC) card

•Call-processing components

The Cisco AS5850 universal gateway basic interfaces are as follows:

•Egress connects to the IP backbone

•Ingress connects from the PSTN

Figure 1 shows the Cisco AS5850 system architecture.

Figure 1 Cisco AS5850 System Architecture

Route-Switch-Controller Card

The route-switch-controller (RSC) card is the main processor card for the universal gateway. It installs in either slot 6 or slot 7 and plugs directly into the backplane, and performs the following functions:

•Transfers data as Fast Ethernet or Gigabit Ethernet packets encapsulated in proprietary protocol. This connection is also used for management.

•For egress, can connect to the IP backbone via two Gigabit Ethernet ports (in Figure 1, the RSC card uses GigabitEthernet6/0 or GigabitEthernet6/1 to connect to the IP backbone).

•Boots and reloads its own Cisco IOS software image.

•Provides source clocks for use by all feature cards and power supplies. Extracts an external reference clock from an external E1 or T1 signal through a BNC connector on the front panel.

•Can connect to an external alarm source through a DB-15 serial connector on the front panel.

•Provides a console port for initial configuration and maintenance.

•Supports SNMP for management information and enables retrieval of syslog information for troubleshooting.

•Provides high availability when configured in handover-split mode.

Note If there are two RSCs in the chassis, they can be configured in classic-split mode or handover-split mode. For more information on configuring the RSC, see the Cisco AS5850 Operations, Administration, Maintenance, and Provisioning Guide at http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5850/sw_conf/ 5850oamp/index.htm.

The Dial Shelf Interconnect Protocol (DSIP) enables communication between RSC and feature cards:

•Trunk cards connect to the public switched telephone network (PSTN) and fit in slots 0-5 and 8-13 only.

–In classic-split mode, the RSC card in slot 6 controls slots 0-5; the RSC card in slot 7 controls slots 8-13.

–In handover-split mode, each RSC can take over the feature cards of the other RSC if that RSC fails.

•Universal port cards also fit in slots 0-5 and slots 8-13, between the trunk cards and the RSC cards. The universal port card supports voice, modem, or fax connections. Each port can carry one DS0 of network traffic.

Call-Processing Components

As shown in Figure 2, the following components process a call:

•Client modems and ISDN routers dial in to the universal gateway through the PSTN.

•Asynchronous PPP calls (analog) connect to ports inside the universal gateway.

•Each port inside the universal gateway provides a corresponding TTY line and asynchronous interface for terminating character and packet mode services.

•Asynchronous interfaces clone their configurations from a group-async interface.

•Synchronous PPP calls (digital) connect to serial interface channels (for example, S0/0:1:23 and S2/0:2:23).

•Synchronous interfaces clone their configurations from a dialer interface.

Figure 2 Cisco AS5850 Call-Processing Components

One asynchronous PPP call requires the following:

•1 DS0 channel

•1 channel in a TDM bus

•1 integrated modem

•1 TTY line

•1 asynchronous interface

One synchronous PPP call requires the following:

•1 DS0 channel

•1 serial interface channel

Note Synchronous PPP calls require HDLC resources. Each T3 trunk card supports 256 HDLC components and each STM1 card supports 512 HDLC components. E1 trunk cards do not have HDLC resource limitations.

System set for auto boot

Possible feature-card states include unknown, down, resetting, booting, and up. The Up state means that a card can communicate with the RSC card.

Each universal port card contains its own DRAM memory and performs its own call processing. A normal CPU utilization range is 20-40%.

Step 2 If the feature card does not come up, perform the following troubleshooting steps.

a. Look for LED lights on the feature card. If the lights are off, try reseating the card.

Note More more information about the feature card LEDs, see the Cisco AS5850 Universal Gateway Card Guide that shipped with this system.

b. Verify that the RSC connection to the other cards is up.

Note Loss of DSIP keepalive messages indicates that there is no communication between the RSC card and the feature cards. After DSIP Hello messages succeed, the backplane Fast Ethernet connection changes its state to Up. Until the interfaces are up, the RSC card and feature cards cannot communicate.

Caution Verify that console logging is disabled. To do so, enter the show logging command and then, if needed, the no logging console command. If logging is enabled, the universal gateway might intermittently freeze up as soon as the console port gets overloaded with log messages.

Messages appear on the console terminal after the feature card is physically removed from slot 12 and reinserted. Approximately 120 seconds elapse before all these messages appear.

The following boot sequence occurs in the previous example:

•The feature card takes 15 seconds to boot up. Afterward, the card checks the system inventory.

•The RSC card loads the appropriate boot images onto the feature cards.

•More than one minute elapses before the RSC card detects the first DSIP Hello message from the first feature card (in slot 12).

•The RSC card gives the feature cards the appropriate images.

c. For advanced troubleshooting of the feature cards after the RSC card is up, open a virtual-console session to the feature card. To end the session, enter Ctrl-C three times.

Note If the show chassis command reports that feature cards are booting for extended periods of time, start debugging from the RSC card by using the following commands:

•debug dsip transport shows the registered MAC address sent from each feature card.

•debug dsip trace displays detailed DSIP hello and keepalive messages.

•debug dsip boot shows whether the RSC card is sending the boot image to the feature cards.

To learn more about these and other Cisco IOS commands, start at http://www.cisco.com/univercd/cc/td/doc/product/software/ and click on your Cisco IOS release.

Use the DSIP Commands

The RSC card communicates with the feature cards using the following:

•Backplane MBUS

•Backplane packet bus

•Backplane Dial Shelf Interconnect Protocol (DSIP)

Note DSIP commands on the Cisco AS5850 function very much like the DSIP commands for the Cisco AS5800. For the DSIP command reference and other system management functions, see Dial and System Management Commands for the Cisco AS5800 at http://www.cisco.com/univercd/cc/td/doc/product/software/ios113ed/113aa/113aa_2/58cfeats/ c5800uas.htm.

To use the DSIP commands, perform the following steps.

Step 1 To understand how DSIP functions, enter commands from the following example.

Note Output from the show dsi command differs from that for the show dsip command.

Explore the Cisco IOS File System

Familiarize yourself with the file system and memory storage areas. The Cisco IOS file system provides a consolidated interface to the following:

•Compact-flash memory file system

•Network file system (TFTP, rcp, and FTP)

•Any other endpoint for reading or writing data (such as NVRAM, SPE firmware, the running configuration, ROM, raw system memory, Xmodem, and flash load helper log)

Figure 3 shows the memory locations inside the Cisco AS5850.

Figure 3 Cisco AS5850 Memory Locations

Table 1 describes the memory types on the Cisco AS5850.

Table 1 Memory Descriptions 

Component
Description

CPU

Central processing unit.

Processor memory

The Cisco IOS software image is initially read out of compact-flash memory, decompressed, and loaded into processor memory (also known as main memory). Routing tables, call-control blocks, and other data structures are also stored here.

Packet I/O memory

Packets are temporarily stored in I/O memory.

disk0:
or
flash:

Compact-flash memory cards in the route-switching module. These cards store Cisco IOS software images, modem firmware/portware, and custom web pages.

bootflash:

Flash memory on the route-switching module.

nvram:

Nonvolatile configuration memory.


To inspect the file system, perform the following steps as appropriate for your system.

Step 1 View the different file storage areas and file management functions. Additionally, verify that you have everything you ordered from manufacturing, such as flash memory. The asterisk (*) near the bottom of the output indicates the current directory.

15990784 bytes total (14100676 bytes free)

Note Keep a backup copy of the RSC Cisco IOS image in boot flash in case compact-flash memory cards are misplaced.

Step 5 Inspect the NVRAM memory on the RSC. Three files are present:

• The initial boot or startup-config.

•The private-config. This is a secure file that supports encryption technologies. It is not user accessible.

•The underlying-config. This is the version of the startup-config that is stored in NVRAM. 

AS5850# dir nvram:

Verify Memory Usage

Use the show memory summary command to do the following:

•Verify how memory is used for different processor and I/O memory processes.

•Identify memory leaks or fragmentation.

–Memory leaks occur when memory is not released back to the processor. They are indicated by steady decreases of free memory. However, the preferred way to track memory leaks is to monitor the FreeMem variable in the OID MIB.

–Memory fragmentation is indicated when the largest block of memory is unequal to the free block. Fragmentation increases as the numbers grow further apart.

To determine and calculate memory usage, perform the following steps.

Step 1 Display the memory status report. In the example, the largest memory block is close to the free-memory block. There is no fragmentation.

Total(b)

Summary of used bytes plus free bytes.

Used(b)

Total number of bytes currently used for routing tables and call-processing components.

Free(b)

Total number of free bytes. Free-memory size should be close to the largest block available.

Lowest(b)

Smallest amount of free memory since last boot.

Largest(b)

Size of largest available free block. When the largest available block is equal to the free block, there is no fragmentation.


Step 2 Convert bytes to megabytes (MB):

•Total processor memory = 479,408,864 bytes = 457.2 MB

•Used processor memory = 44,937,912 bytes = 42.9 MB

•Free processor memory = 434,470,952 bytes = 414.3 MB

Total memory (457.2 MB) = Used memory (42.9 MB) + free memory (414.3 MB)

Step 3 Do some useful memory calculations:

Total Processor = Total RAM - Cisco IOS software (use the show version command to get the MB assigned for all of Cisco IOS software + processor) 

cisco c5850 (R7K) processor (revision 0.12) with 491520K/32768K bytes of memory.

491520K = 480 MB

+  32768K = 32 MB

Total = 512 MB (what you purchased)

Verify CPU Utilization

High utilization causes network performance problems. Knowing when the gateway is running at over 50% utilization is critical because the gateway might start dropping packets if an unexpected traffic burst comes through, or if OSPF gets recalculated. Fast switching reduces CPU utilization.

To verify CPU utilization, perform the following steps.

Step 1 Verify CPU utilization. 

AS5850# show processes cpu


CPU utilization for five seconds: 0%/0%; one minute: 0%; five minutes: 0%
