Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
router rip
network 10.0.0.0
default-metric 2
distribute-list 49 out Ethernet1/2.10
Workaround: There is no workaround.
• CSCsv80014
Symptoms: When doing an SNMP walk on OLD-CISCO-IP-MIB when the routing table has several
thousand prefixes, excessive CPU utilization occurs.
Conditions: The symptoms are seen only when there are several thousand prefixes in the routing
table.
Workaround: Exclude the OLD-CISCO-IP-MIB from the SNMP walk. This MIB has been
deprecated.
• CSCsv81009
Symptoms: Intermittent traffic loss occurs on switch virtual interface (SVI) enabled with Virtual
Router Redundancy Protocol (VRRP). Cannot ping VRRP IP address.
Conditions: Occurs with VRRP configured on SVI. Traffic loss/ping VRRP IP address failure seen
sometimes on bootup.
Workaround: If VRRP mac-address is present as dynamic entry on bootup, this issue can be seen.
Reconfigure VRRP as a workaround.

Symptoms: Cisco 7200 G2 router crashes when changing configuration of serial interfaces from PPP
to SDLC and back to PPP, while running traffic.
Conditions: This is observed on a T3 link with 56 channel groups configured on a WAN aggregation
device. All the serial interfaces have service-policy configured.
Workaround: Remove the service-policy before changing the encapsulation to SDLC.

Symptoms: When accounting is enabled for virtual private dial-up network (VPDN), there might be
messages with termination cause “nas-error” and displaying impossible values in Acct-Input-Octets,
Acct-Output-Octets, Acct-Input-Packets and Acct-Output-Packets.
This causes accounting to be unreliable.
Conditions: Occurs with Cisco IOS Release 12.4T and configured for PPTP/L2TP with accounting.
Workaround: There is no workaround.
• CSCsv85990
Symptoms: If there are multiple EFPs with, for example encapsulation 100, same encapsulation on
different interfaces and with different bridge-domains configured for Virtual Private LAN Services
(VPLS), then if there is a topology change notification (TCN) received on one of the Ethernet Flow
Points (EFPs) on one interface, then Label Distribution Protocol (LDP) MAC address withdrawals
are sent for all the bridge domains on all the interfaces.
Conditions: Occurs when the network has EVCs on the L2-Access forwarding to VPLS core.
Multiple Spanning Tree (MST) is running on the access VLANs.
Workaround: There is no workaround.
