Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8

OL-10394-05 Rev. R0

The PPP session is established with the Cisco 7301, which is ISG enabled.

When traffic reaches 1 gigabyte, the accounting attribute will be corrupted with 2^32 - 1.

The expectation of the gigabyte word is when it reaches 4294967295 bytes, it will increment with 1

gigaword.

The problem is seen in the following releases:

Cisco IOS Release 12.2(31)SB11: per-user service account corrupts the gigaword, and per-user

session is correct.

Cisco IOS Release 12.2(31)SB12: per-user service account corrupts the gigaword, and per-user

session does not show anything at all.

Cisco IOS Release 12.2(33.1.10)SB1: per-user service account shows nothing in the gigaword, and

per-user session is correct.

Conditions: When traffic reaches 1 gigabyte, the accounting attribute will be corrupted with 2^32 -

Workaround: There is no workaround.

Symptoms: Autoinstall process does not run correctly with a BOOTP or DHCP server in same LAN.

Because of the problem, the configuration file may not be downloaded using TFTP from the network

during autoinstall.

Conditions: The symptoms are observed with a Cisco 7200 series router that is running Cisco IOS

Release 12.4(21.06)T01. It is observed with a BOOTP server and when the DHCP client and TFTP

server are in same LAN. The client is configured to obtain an ip address for an interface (using the

ip address dhcp command) and then the DHCP client configuration is copied to TFTP. The

autoinstall process is started using "write erase and reload". It shows that no BOOTP information is

received. The DHCP client downloads the hostname.confg file from TFTP. As a result, the

configuration (using the ip address dhcp command) is missing on the interface.

Workaround: There is no workaround.

• CSCsr17680

Symptoms: AA-request, sent to a particular server, getting failed-over to all other servers in the

server group, when the first server is not responding or first server is unreachable.

Conditions: This issue is observed when sending request to particular server on a server-group.

Workaround: There is no workaround.

• CSCsr18589

Symptoms: A Virtual Router Redundancy Protocol (VRRP) group configured on a VLAN interface

flaps from the backup to the master state after stateful switchover (SSO) when the existing master

is still available on the network. The group will flap back to backup a short period later.

Conditions: The problem only occurs when there are a large number of VLAN interfaces with a

VRRP group configured on each interface and SSO is performed.

Workaround: Each of the VRRP groups can be configured with a larger VRRP advert timer value.

Values should be varied depending on the setup, but a larger than default value is usually required.

• CSCsr18942

Symptoms: Traceback occurs when VPN routing/forwarding (VRF) is deleted and then recreated.
