Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
- Affects 12.2(33)SRC or later, but not earlier versions.
- Slow response to console commands.
- Netflow enabled on point-to-point interfaces
- High number of IPv4 routes learned via BGP.
Workaround: Downgrade to the latest release of 12.2(33)SRB. During high CPU condition, do the
following:
1. Remove ALL interface level and global netflow configurations.
2. Configure global command: cef table output-chain build favor convergence-speed.
3. Re-apply global and interface level netflow configurations.
The cef table ... command mentioned above will stay in the configuration. This command should
stop this issue from re-occurring.

Symptoms: Igmp-proxy reports for some of the groups are not forwarded to the helper. This causes
members not to receive the multicast traffic for those groups.
Conditions: The problem is seen when the igmp-proxy router is receiving UDP control traffic. That
is, the router is receiving any UDP control-plane traffic on any interface.
Workaround: There is no workaround.

Intercept (LI) service module after a line card online insertion and removal (OIR), the SIP-400 may
not get selected as Lawful Intercept service module.
Conditions: Occurs when the SIP-400 is configured as Lawful Intercept service module on the Cisco
7600.
Workaround: After line card OIR, select the SIP-400 again as the LI service module using the
command li-slot list <sip400 slot number>.

Symptoms: Intelligent Services Gateway (ISG) traffic from one user to another may fail if the packet
needs to be processed by the RP in a Cisco 7600.

second subscriber.
Other symptoms : - Counters of packet transfer might show difference between user transferring
between each other - Access-list might fail to block the packet
The 2 above symptoms will be seen when user are sending receiving on the same interface via the
ISG
Workaround: There is no workaround.
