3. Modify each defined community string to include the view nolsrmib keywords. For example,
define the “public” community string by entering the following command:
snmp-server community public view nolsrmib ro
4. Enter the no shutdown interface configuration command on all the interfaces that you shut
down in Step 1.

Symptoms: An LSP ping may not interoperate with third-party vendor equipment. The following
commands may either timeout or receive an error return code from third-party vendor equipment:
– ping mpls ipv4 ip-address address-mask
– trace mpls ipv4 ip-address address-mask
– ping mpls pseudowire peer-id vc-id
Conditions: This symptom occurs because of recent changes to the ietf-mpls-lsp-ping-06.txt draft,
preventing Cisco’s implementations of LSP pings from interoperating with third-party vendor
equipment.
The recent draft changes include the following:
– “Implicit padding” of the Target FEC TLV subtype lengths is required when pinging an LDP
IPV4 FEC.
– The FEC definition that is used in the ping mpls pseudowrire command now requires Target
FEC TLV subtype 10 instead of 9.
Workaround: There is no workaround.

Symptoms: When 1000 input ACLs are configured on an Engine 3 line card and when traffic is
denied by the input ACL, the following error message and traceback are displayed continuously on
the console:
%GRP-4-NO_INTF: CSAR: No interface available Slot 4 Chan 19
-Traceback= 1ADD94 44A2E4 44A988 44BD94 44C3D0 4451D8 27CCB0
This symptom occurs whether the router is configured with a GRP, a PRP-1, or a PRP-2. When the
router is configured with a PRP-1 or PRP-2, the output of the show controllers psar | incl idb shows
the following:
No IDB drops - 3423 IDB queue tail drops - 0 CORE2-R2#
However, the output of the show idb command shows that there are 32 IDBs.
When the router is configured with a GRP, the output of the show controllers csar does not show
anything unusual.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0(27)S1 or
Release 12.0(27)S2a only when an input ACL is applied, when traffic is denied by the input ACL,
and when the ip unreachable command is enabled on the interface of the Engine 3 line card.
Workaround: Enter the no ip unreachable command on the interface of the Engine 3 line card.

Symptoms: An SRP interface is stuck and there is no response at all. In the output of the show srp
topology command, the last topology packet that is received takes more than five seconds to arrive.
In addition, the “zero encap length” counter in the output of the show hardware pxf cpu stat
interface srp 1/1 detail command increases.
Conditions: This symptom is observed on a Cisco 10720 when the value of the overall packet size
divided by 32 is 1 or 2.
