Upgrading NAM Software

NAM 3.5.1a is a complete software release, not a patch. To upgrade NAM 3.4 to version 3.5.1a, enter the NAM CLI command upgrade while in maintenance mode. For information about the upgrade command see the Network Analysis Module 3.5 Command Reference Release at the following URL:

http://www.cisco.com/en/US/products/hw/switches/ps708/products_command_reference_chapter09186a00805e34f0.html#wp1048351

You can apply the NAM 3.5.1 Crypto K9 patch, nam-app.3-5.cryptoK9.patch.1-0.bin, on top of NAM 3.5.1a using NAM CLI command patch.

NAM Disk Partitioning

NAMs that shipped prior to NAM 3.3 might still be using an older and less efficient disk partitioning system. The NAM 3.3 release increased the size of the /storage partition to 12 gigabytes to handle the NAM's increased data capture capabilities.

Note This condition affects the NAM-1 and NAM-2 but not the NM-NAM.

If your NAM's /storage partition is only 3.4 GB, you can increase its size to 12 GB by reloading the NAM software with the 3.5(1) image using the --install option.

You can check your disk's partitioning using the GUI by clicking Admin > Diagnostics > Tech Support and checking the df heading. The following shows an example of the old partitioning with only 3.4GB of space /storage: 

Filesystem           1K-blocks       Used  Available   Use% Mounted on

LABEL=/                4128320     243476    3675108     7% /

/dev/hdc2              1032056      33460     946156     4% /nvram

/dev/hdc3              3451192     183208    3092668     6% /storage

/dev/hda1                15860      10089       4947    68% /mnt/mp

The following shows an example of the newer partitioning with only 12 GB of space /storage: 

Filesystem          1K-blocks       Used  Available   Use% Mounted on

LABEL=/               4128320     243912    3674672     7% /

/dev/hdc2             1032056      34284     945332     4% /nvram

/dev/hdc3            12385072     197792   11558112     2% /storage

/dev/hda1               15860      10102      4934     68% /mnt/mp

Note You can also check your disk partition sizes using the OS shell command df.

To increase your disk partitioning to the correct size, you can reload the 3.5(1) image using a command like the following:

upgrade ftp://ftpusername@ftp-server-ip/path/nam-image-filename --install

Where:

ftpusername is the username of the individual performing the FTP access.

ftp-server-ip is the IP address or hostname of the FTP server.

path is the path to the image on the FTP server.

nam-image-filename is the filename of the NAM image to install.

TAC Case Priority Definitions

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.

Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
