Caveats

Resolved Caveats—Cisco IOS Release 12.0(33)S2

Workaround: There is no workaround.

• CSCsr11332

Symptoms: In rare situations, the show controller SONET port command might crash the RP.

Conditions: This symptom has been observed on a 4CHOC12/DS3-I-SCB= line card, but it can be

seen on other similar channelized line cards. It may be reproducible by executing the show

controller SONET port command on a nonexistent port like sonet 3/4 (that is, only sonet 0/0, 0/1,

0/2, and 0/3 are valid on a 4CHOC line card). When the problem can be seen, the CLI help indicates

an incorrect unit number:

Router# show controller sonet 12/?

<0-48> Controller unit number

If the controller unit number is shown fine (for example, <0-3>), then the crash will not occur.

Workaround: There is no workaround.

• CSCsr13314

Symptoms: The pos delay triggers line command is configurable on APS-enabled interfaces of E3

clear channel POS line cards. After the commit of CSCsq45452, the pos delay triggers path

command is not configurable on APS-enabled interfaces of E3 channelized POS line cards.

Conditions: This symptom is observed on a Cisco 12000 series Internet router that is booted with

Cisco IOS Release 12.0(32)S. The router contains ISE OC48 POS and ISE CHOC48 POS line cards.

Workaround: There is no workaround.

• CSCsr13521

Symptoms: Memory chunk allocated for LDP-IGP Sync may leak.

Conditions: The symptom is observed on a router with a dual link to its neighbor. LDP and LDP

Graceful Restart are enabled on both routers. When LDP is disabled and re-enabled globally on the

neighbor router, a small memory leak occurs on this router.

To verify the memory leak, on Router 1, enable memory leak debug with the set memory debug

incremental starting-time command. On Router 2, disable LDP globally with the no mpls ip. Wait

for LDP session go down, then re-enable LDP. On Router 1, the memory chunk leak for LDP should

be seen with the sh mem debug leaks chunks command.

Workaround: There is no workaround.

• CSCsr18851

Symptoms: When the router reloads, it loses the previously configured wavelength configuration

and puts the controller at its default wavelength (channel 3), which is an undesirable behavior.

Conditions: This symptom is observed with Cisco IOS Release 12.0(33)S01 and an

SPA-1X10GE-L-ITUC when a specific wavelength in the controller is configured (for example,

wavelength itu-channel 41), the write memory command is issued, and then the router is reloaded.

Workaround: There is no workaround.

• CSCsr20377

Due to an eng3 HW limitation, there is more overhead added to like to like ethernet PW or ethernet

interworking PW if “hw-module slot <> qos account layer2 encapsulation length <>” is configured.

without the fix of CSCsq42803, the overhead impact is less. Request a return to the behavior of

12.0(32)SY back to pre-CSCsq42803.

• CSCsr22043

Symptoms: A controller goes into an admin down state.
