Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: Deletion of one sub-interface with L2TPv3 cross connect configuration may cause the
others L2TPv3 sessions in other sub-interfaces to go down.
Conditions: The symptom is seen with the Cisco IOS Release 12.2(33)SRD only. It is observed when
there is sub-interface with L2TPv3 cross connect configuration, such as:
l2tp-class vlan-class authentication password x xxxxxxxx
pseudowire-class vlan-pw encapsulation l2tpv3 protocol l2tpv3 vlan-class ip local
interface Loopback0
interface GigabitEthernet0/1.1 encapsulation dot1Q 2 xconnect 10.200.1.203 2 pw-class
vlan-pw ! interface GigabitEthernet0/1.2 encapsulation dot1Q 3 xconnect 10.200.1.203 3
pw-class vlan-pw ! The problem occurs when one sub-interface is deleted, for example:
no interface GigabitEthernet0/1.1
Workaround: There is no workaround.
• CSCsq55691
Symptoms: QoS with Link Fragmentation and Interleaving (LFI) over ATM does not work.
Conditions: Occurs after a shut/no-shut on the ATM interface
Workaround: Reload the line card on both ends.
• CSCsq57462
Symptoms: Ethernet Out of Band Channel (EOBC) hang causes line card reset. EoBC might get
stuck resulting in communication loss between RP/SP and line card. This will result in line cards
getting reset. This is a very rare condition and is seen only once so far.
Conditions: Occurs during increased EoBC traffic due to convergence or link flap and is very rarely
seen.
Workaround: This impacts only one CPU. A forced switchover will recover from this condition.
• CSCsq58385
Symptoms: Cannot ping Hot Standby Routing Protocol (HSRP) virtual address when active on ES20
card.
Conditions: This symptom is observed on a Cisco 7600 series router with SUP720, ES20 and
running Cisco IOS Release 12.2(33)SRB3.
Workaround: There is no workaround.
• CSCsq60073
Symptoms: An OSPF router process may experience high CPU load, after shutting down the OSPF
graceful shutdown process.
Conditions: The symptom is observed if the OSPF graceful shutdown is configured together with
MPLS TE.
Workaround: Do not shutdown the OSPF process when configured for MPLS TE.
• CSCsq60553
Symptoms: An FW2 card may reload with memory version "VI4DP647228EBK-MD" installed.
Conditions: The symptom is observed with all FW2 linecards having Memory version
"VI4DP647228EBK-MD".
Workaround: There is no workaround.
• CSCsq62653
Symptoms: A router may crash if the show subscriber command is executed on the VTY followed
by a clearing of the main session.
