Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
CSCsl79219
Symptoms: Bidir shadow entries may not be installed in hardware thus blocking the multicast traffic
in some conditions.
Conditions: This symptom occurs on the Cisco Catalyst 6500 switch that is running with MVPN
configuration. The core network is in PIM-Bidir mode and sometimes the "z" flag setting for data
MDT groups is not populated to hardware.
Workaround: Use the clear ip mr mdt_group command to solve the problem.
CSCsl80682
Symptoms: VPN SPA crashes when encryption ACLs are modified.
Conditions: Was seen happening when GRE takeover configured (GRE acceleration being done by
SPA): crypto engine gre vpnblade
Workaround: Configure GRE acceleration to be done by supervisor: crypto engine gre supervisor.
CSCsl80870
Symptoms: While bringing up 20 MLPoATM bundles with 10 member links, a few member links
fail to come up.
Conditions: This symptom occurs when some of the member links are inactive when the bundles
come up.
Workaround: There is no workaround.
Further Problem Description: The cause for this issue is the bundle auth type does not match with
the current links auth type. The current link name does not match the bundle first link name.
CONFREJ is sent, and the member is removed from the bundle.
CSCsl80887
Symptoms: The router may crash and there is high CPU usage if the Routing Information Protocol’s
(RIP) minimum update interval is configured to zero.
Conditions: The symptom may be observed on a Cisco router using RIP version 2 process, with the
timer values set to 0 1 0 1.
Workaround: Do not configure RIP’s minimum update interval to zero.
CSCsl81011
Symptoms: Hierarchical queuing framework (HQF) not cleared even after removing the service
policy from the interface.
Conditions: HQF hierarchy not cleared after entering the no service-policy out <pname>command.
This is seen with Optical Services Module (OSM).
Workaround: There is no workaround.
CSCsl81012
Symptoms: Cisco 7600 configured with SSO High Availability, with large number of EVC with
bridge-domain, may experience a crash during bootup. Occurs while the standby supervisor is
coming up.
Conditions: This happens in the following conditions:
- Cisco 7600 with dual supervisor in SSO redundant mode.
- During bootup, after active RP booted and standby RP is coming up (HA syncing is happening).
- LC reloads (which can happen when the card is first brought up during boot).
