Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: When sending packets that exceed specified MTU, packets are received as giants in
PA-T1/E1 IMA card instead of being fragmented.
Conditions: It happens only after changing sub-interface MTU and after stateful switchover (SSO).
Workaround: Perform a shut/no shut on the main interface.
CSCsw70125
Symptoms: A Cisco 7600 SIP-400 with POS interfaces encapsulated with IETF frame-relay may
incorrectly set 0x800 as Network Layer Protocol Identifier (NLPID) for hardware assisted multicast
IP packets. The correct value is 0xCC.
Conditions:
A. IP unicast packets in hardware path do not have this problem.
B. IP multicast or unicast packets in software path do not have this problem.
C. Problem reproducible in Cisco IOS Release 12.2(33)SRA2, 12.2(33)SRA7, and 12.2(33)SRC2.
Workaround: There is no workaround.
CSCsw71208
Symptoms: Cisco 7600 does not respond properly to Link Control Protocol (LCP) echo requests,
causing PPP sessions to renegotiate between the router and non-Cisco devices.
Conditions: Occurs on a Cisco 7600 running Cisco IOS Release 12.2(33)SRC2.
Workaround: Disable keep-alives on the non-Cisco device.
CSCsw72677
Symptoms: Router crashes with “no bba-group pppoe”.
Condition: Happens after unconfiguring “bba-group”.
Workaround: There is no workaround.
CSCsw73863
Symptoms: IDs allocated from DHCP are leaked, causing the device to reload.
Conditions: Device is configured as Cisco Intelligent Services Gateway (ISG) DHCP with 24000
sessions flapping every 10-12 minutes.
Workaround: There is no workaround.
CSCsw73956
Symptoms: During health monitor failure, platform action was taken immediately but platform
action should be taken from gold TCL policy.
Conditions: Occurs when health monitor test failure crosses failure threshold.
Workaround: There is no workaround.
CSCsw75589
Symptoms: If you have configured Netflow and also have “ip flow-cache mpls label-positions”, you
are very likely to run in a bus error crash with info similar to what is seen here:
%ALIGN-1-FATAL: Illegal access to a low address 10:28:28 UTC Sat Dec 20 2008
addr=0x1E, pc=0x61CB7180, ra=0x61CBA5C0, sp=0x65BCAF20
%ALIGN-1-FATAL: Illegal access to a low address 10:28:28 UTC Sat Dec 20 2008
addr=0x1E, pc=0x61CB7180, ra=0x61CBA5C0, sp=0x65BCAF20
10:28:28 UTC Sat Dec 20 2008: TLB (store) exception, CPU signal 10, PC = 0x61CB7180
Conditions: Problem is platform independent but specific to IOS release. This problem is seen in
12.2(33)SRC1 and possibly affects 12.4T releases as well.
