Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Symptoms: "Circuit-id-tag" and "remote-id-tag" attributes may be duplicated in packets sent to the
RADIUS server.
Conditions: The symptom is observed with Cisco IOS Release 12.2(31)SB13.
Workaround: Use Cisco IOS Release 12.2(31)SB14.
CSCsv73735
Symptoms: After performing a redundancy switchover (RPR+ mode), the ARP table is not correctly
populated. Entering the clear ip arp or the clear arp-cache commands, then pinging the connected
CE or PE causes an incomplete entry to be added to the ARP table.
Conditions: This is seen on Gigabit Ethernet, FastEthernet and POS interfaces. ATM and serial
interfaces seem do not appear to be affected. This behavior is not seen with stateful switchover
(SSO).
Workaround: There is no workaround.
CSCsv79993
Symptoms: A Cisco 7600 may crash when a distribute-list is deleted.
Conditions: Crash occurs when removing a distribute-list from EIGRP. The distribute-list was one
of many that was sharing the same route-map and access-list. The crash only happens when multiple
protocols have the same direction distribute-list configured on the same interface, as in the following
example:
router eigrp 10
network 10.0.0.0
distribute-list 49 out Ethernet1/2.10
router rip
network 10.0.0.0
default-metric 2
distribute-list 49 out Ethernet1/2.10
Workaround: There is no workaround.
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.
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.
