Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: Execute the show ip arp interface command and the ip address command
configuration sequentially.
CSCsm13408
Symptoms: DHCP renew packets are ignored after a switchover.
Conditions: This is only present after a forced switchover from Active to Standby RP, and only for
VPN routing/forwarding (VRF) ip-sessions.
Workaround: Prevent switchover, or extend the DHCP lease time to 24 hours or more.
CSCsm13783
Symptoms: MVPN PIM adjacency cannot be established over the MDT tunnel.
Conditions: The very basic functionality of MVPN is not functioning, because of which no multicast
traffic can flow between PE2 and PE1.
Workaround: There is no workaround.
CSCsm14007
Symptoms: ifOutOctets and ifHCOutOctets are 0 and not being incremented for some Virtual
Access interfaces.
Conditions: This symptom is observed on a Cisco 10000 router that is running Cisco IOS Release
12.2(31)SB6.
Trigger: Unknown.
Impact: Monitoring and troubleshooting of Virtual Access interfaces using SNMP are impacted.
Workaround: There is no workaround.
Further Problem Description: Interface counters as seen in the output from the show interface
command are incrementing okay. ifInOctets and ifHCInOctets are incrementing. The problem is
affecting only some Virtual Access interfaces, not all.
CSCsm14833
Symptoms: All incoming ISDN calls are rejected.
Conditions: This symptom occurs when a Cisco IOS router is:
- equipped with NPE-G2. - configured for ISDN dial-in with multiple Dialer Profiles.
This is seen in devices (Cisco 7206VXRs) that are configured for ISDN PRI dial- in with Dialer
Profiles for backup purposes.
The problem could be reproduced in the lab where ISDN BRI i.o. PRI line is in use:
- When only 1 Dialer Profile is configured, all incoming ISDN calls are bound to it by default. -
When 2 Dialer Profiles are configured in the same pool, all incoming ISDN calls were rejected due
to "Incoming call rejected, unbindable".
The Caller ID or DNIS binding cannot be used as all incoming ISDN calls have no Caller ID and
the same DNIS.
Workaround: Upgrade to Cisco IOS Release 12.4(11)T or later releases, which also support
NPE-G2.
CSCsm15350
Symptoms: The VPNSPA may crash with an assert failure.
Conditions: The symptom is observed when B2B is configured and when creating 8000 remote
access sessions.
