Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S
Workaround: Either remove dCEF or remove LFI. (A combination of CEF and MLP is not
supported.) Note that if there are two member links in the interleaving-enabled MLP bundle, the
problem does not occur.
• CSCee24263
Symptoms: A PVC may be inactive and may not come up.
Conditions: This symptom is observed when a VC is deleted or removed and you try to recreate the
same VC.
Workaround: Save the configuration and reload the router.
• CSCee30549
Symptoms: Some interfaces on a channelized SONET line card may not carry bidirectional traffic
following an APS switchover. Interfaces may be up and routes may be present when this occurs.
Conditions: The symptom is only observed on a Cisco 12000 series 1-port OC-12 line card
(channelized to DS1) that functions in an 1+1 APS configuration. The symptom could occur on any
channelized APS interface.
Workaround: Enter the shutdown command followed by the no shutdown command on the affected
interfaces.
• CSCee35349
Symptoms: When you set up an L2TPv3 tunnel configured in the PW class, a ping cannot go through
from CE router 1 to CE router 2 until the ping is initiated by CE router 2.
Conditions: This failure occurs in Cisco IOS Release 12.0(28)S with a Fast Ethernet interface (not
with a serial or POS interface).
Workaround: First, ping from CE router 2 to CE router 1. Then, ping from CE router 1 to CE
router 2.
• CSCee36744
Symptoms: An RP may crash when you add or remove a channel group to or from a 4-port ISE
Gigabit Ethernet line card or when you reload microcode onto the line card on which channel group
members are configured.
Conditions: This symptom observed on a Cisco 12000 series when there are link-bundle
subinterfaces configured on the 4-port ISE Gigabit Ethernet line card. A list of the affected releases
can be found at http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCed63480.
Cisco IOS software releases that are not listed in the “First Fixed-in Version” field at this location
are not affected.
Workaround: There is no workaround.
• CSCee40938
Symptoms: FRoMPLS traffic fails with an Engine 3 line card as the disposition card.
Conditions: This symptom is observed with any DLCI (xx xxxx xx11) that uses the two LSBs in its
“ckt” ID. This problem is seen because of the corruption of the two LSBs during a disposition
update.
Workaround: There is no workaround.
• CSCee42281
Symptoms: Some interfaces on a channelized SONET line card may not carry bidirectional traffic
following an APS switchover. Interfaces may be up and routes may be present when this occurs.
