Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
• CSCsq43591
Symptoms: When a session is cleared from the CPE and when it reconnects instantaneously, a ping
fails to the CPE.
Conditions: This symptom is observed under the following conditions:
- LAC<->LNS setup. - Clearing of session from CPE. - In the show pxf cpu vcci command output,
there is no VCCI present for the VAI. - Also seen in lab when the CPE is booted and the first session
comes up.
Workaround: Clear the VAI interface from the LNS. The session will reconnect and will work fine.

Symptoms: A Cisco 7300 NSE may experience multiple unexpected reloads due to an address error.
Conditions: The symptom is observed with QOS configuration policing on the outbound traffic.
Running output policer on a packet that has not been classified causes the unexpected reload.
Workaround: There is no workaround.

Symptoms: A Cisco IOS router may unexpectedly reload when Forwarding Information Base (FIB)
processes an adjacency for route that has many levels of recursion.
Conditions: This has only been seen after the following error message was displayed:
%COMMON_FIB-6-FIB_RECURSION: 10.10.10.1/32 has too many (8) levels of recursion during
setting up switching info
Workaround: Change static routes so they specify both the interface and next-hop instead of just
specifying the next-hop. For example change
ip route 10.0.0.0 255.255.255.255 192.168.1.1
to
ip route 10.0.0.0 255.255.255.255 GigabitEthernet1/0 192.168.1.1
This is particularly true when using eBGP between loopbacks to allow for multiple parallel links
between the two eBGP peers, where one typically installs static routes for the eBGP peers address.
Make sure these static routes have both interface and next-hop specified.

Symptoms: When configuring "is-type level-1" under "router isis", the following error message may
be received:
% Ambiguous command: "is-type level-1"
Conditions: The symptom is observed when configuring "is-type level-1" under "router isis".
Workaround: There is no workaround.

Symptoms: A PA-POS-2OC3 experiences an output stuck condition.
Conditions: This issue is sporadic in nature and is sometimes seen with QoS configurations although
QoS is not the cause of the issue. The issue is due to an extra interrupt, which is confusing the driver
if it expires before the FIFO reaches the low point. For example, if the FIFO goes full but is filled
with large packets, then it is possible that the no traffic timer will expire before the tx packets have
emptied. It is a communication issue between the hardware and the driver code.
Workaround: There is no workaround.
