Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: Configure subinterface in "non-native" mode.
CSCsv13738
Symptoms: There are two ways to define VRFs when supporting the 6VPE feature: 1) ip vrf 2) vrf
definition. The "vrf definition" configuration may take a much longer time to allow convergence
between the PE and the CE than the "ip vrf" configuration.
Conditions: The symptoms are observed under the following conditions: - when the router boots up;
and - when the issue has been seen using the "vrf definition" configuration; and - when the router
has over 100,000 VPNv4 BGP routes; and - when a large number of VRFs are configured.
Workaround: Use the "ip vrf" configuration, if you have only IPv4 VRFs configured.
CSCsv13914
Symptoms: Traceback observed when the PPPoEoA session is brought up.
Condition: Occurs when the interface is not up.
Workaround: There is no workaround.
CSCsv15040
Symptoms: Infinite Loop occurs when doing MIB walk on cdot1agStackTable objects.
Conditions: Occurs on a Cisco 7600 running Cisco IOS Release 12.2(33)SRD and configured with
10GE-XFP-SPA and SIP-600 configured for Distributed Forward. This problem is seen when
"MIP/MEP" configured on Te1/0/0 interface and MIB walk is performed on cdotagStackTable
objects.
Workaround: Do not configure "MIP/MEP" on Te1/0/0 interface.
CSCsv16869
Symptoms: BGP updates may not be sent out.
Conditions: The symptom is observed when neighbors are flapped in a large- scale scenario.
Workaround: There is no workaround.
CSCsv20125
Symptoms: PPPoE sessions over VLAN over ATM with process switch stuck at LCP stage.
Conditions: Occurs when the protocol pppovlan command is configured on ATM subinterface
along with no ip cef. PPPoE sessions are not created.
Workaround: Use the ip cef command.
CSCsv21295
Symptoms: Due to TestLoopback diagnostic failure on RSP supervisor, the interface is placed to
err-disable state.
Conditions: This is seen when the interface is configured as RJ45 and with speed between 10 to
100mbps.
Workaround: Configure the speed on RJ45 interface ’auto’ negotiation and execute the diagnostic
test TestLoopback to get the port out of err-disable.
CSCsv21403
Symptoms: Traffic is not passed through an Ethernet Virtual Circuit (EVC) service instance.
Conditions: Occurs after configuring EVC (Ethernet Virtual Circuit) service instance. The show
platform efp-client command shows no output.
Workaround: There is no workaround.
