Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(33)S3
Conditions: This symptom is observed upon SSO switchover.
Workaround: Reload the RP.
CSCsu63081
Symptoms: The delay triggers path delay command does not function as it is provisioned on an
E3 CHOC12 controller.
Conditions: This symptom is observed on a Cisco 12000 Internet series router booted with
c12kprp-p-mz.120-32.S11n. This router contains an E3 CHOC12 line card.
Workaround: There is no workaround.
CSCsu65189
Symptoms: If router is configured as follows:
router ospf 1
...
passive-interface Loopback0
And is later enabled with LDP/IGP synchronization using the following commands.
Router(config)# router ospf 1
Router(config-router)# mpls ldp sync
Router(config-router)# ^Z
MPLS LDP/IGP synchronization will be allowed on the loopback interface too.
Router# show ip ospf mpls ldp in
Loopback0
Process ID 1, Area 0
LDP is not configured through LDP autoconfig
LDP-IGP Synchronization : Required < ---- NOK
Holddown timer is not configured
Interface is up
If the clear ip ospf proc command is entered, LDP will keep the interface down. Down interface is
not included in the router LSA, therefore IP address configured on loopback is not propagated. If
some application like BGP or LDP use the loopback IP address for the communication, application
will go down too.
Conditions: Occurs when interface configured as passive. Note: all interface types configured as
passive are affected, not only loopbacks.
Workaround: Do not configure passive loopback under OSPF. The problem occurs only during
reconfiguration.
The problem will not occur if LDP/IGP sync is already in place and:
The router is reloaded with image with fix for CSCsk48227.
The passive-interface command is removed/added.
CSCsu66119
Symptoms: If “set exp” is configured on the ingress AC, local switching (AC - AC) traffic does not
copy the exp value to the cos bits in the egress direction.
Conditions: This symptom is observed with E3 as ingress and “set exp” configured on VPLS
interface.
Workaround: There is no workaround.
