Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: The symptoms occur when synchronizing a virtual template/virtual access interface
configuration from the active to the standby.
Workaround: There is no workaround if virtual access interfaces are required.
• CSCso72167
Symptoms: The ISSU AAA client negotiation says the session is COMPATIBLE with the images,
even though the standby is loaded with an image that does not support that client.
Conditions: The symptoms are observed when there is a stale ISSU AAA client on the ACTIVE,
which does not clear the session once the standby goes down.
Workaround: There is no workaround
• CSCso72541
Symptoms: The show ipv6 mfib active yields the following error message:
"%MFIB_STATS-DFCx-x-MFIB_STATS_LC_FAILED_GET_COUNTERS: Linecard failed in getting
counters due to null table"
Conditions: The error message is seen when we have active IPv6 multicast sources sending packets
at a rate greater than 4 kbps.
Workaround: There is no workaround.
• CSCso73266
Symptoms: L4-redirect intermittently fails. CoA Nack is returned to the redirection server.
Conditions: These symptoms can occur in a high-traffic situation in which many requests need to be
handled by the ID manager database.
Workaround: Reload the router running ISG.
• CSCso73533
Symptoms: Traceback is seen after unconfiguring the tunnel interface.
Conditions: The symptom is seen when using Ipv4 multicast PIM tunnels where the route to the
Rendez-Vous Point (RP) is via another tunnel interface. If this tunnel interface was unconfigured,
then there is a race condition between: 1. learning about the new route to the RP via another
interface; and 2. periodic update of the PIM tunnel adjacency. If the latter occurs first the traceback
is seen
Workaround: There is no workaround.
• CSCso74028
Symptoms: The local PE is sending graft messages even after receiving data from the remote PE on
an MVPN network.
Conditions: This symptom is observed when the graft-ack messages are lost in transit (could be due
to misconfiguration/ACL, etc.).
Workaround: Fix the misconfiguration so that graft-ack messages are forwarded as expected.
• CSCso74156
Symptoms: Feature push for VRF-tx does not work.
Conditions: On the service profile, a "vrf-id=..." is configured. This is pushed onto a session. IPCP
renegotiation fails on Client Router.
Workaround: Within Cisco IOS Release 12.2(31)SB images, the cloning Virtual- Template interface
did not require the ip unnumbered X command when running Cisco IOS Release 12.2(33)SB. The
cloning Virtual- Template interface requires the ip unnumbered X command statement similar to
the notation below:
