Chapter
Caveats in Cisco IOS XE 3.7S Releases
• CSCtz77491
Symptoms: The router stops passing traffic and crashes.
Conditions: Occurs when you remove a QoS policy applied to a trunk EFP.
Workaround: There is no workaround.
• CSCtz82725
Symptoms: The router intermittently drops packets.
Conditions: Occurs on 10 Gigabit Ethernet core links when the router passes traffic for an extended
period and running a VPLS-TP configuration.
Workaround: There is no workaround.
• CSCtz87262
Symptoms: The router’s convergence time is greater than 90 seconds when you clear the multicast
routing table.
Conditions: Occurs with a ring topology with 2 parallel paths from the FHR to the LHR Receivers.
Workaround: There is no workaround.
• CSCtz90273
Symptoms: The router duplicates multicast traffic when configured as a static rendezvous point
(RP) node.
Conditions: Occurs under either of the following conditions:
– You remove Auto RP announce configurations on all routers.
– You configure the router as a static RP and enable multicast traffic
Workaround: Select an RP mode: static, auto, or bootstrap router (BSR) and avoid switching
dynamically between RP modes.
• CSCtz92857
Symptoms: MAC learning fails and the router displays FIFO table overflow messages.
Conditions: Occurs with a MAC security configuration running at high scale.
Workaround: There is no workaround.
• CSCtz92914
Symptoms: L3 multicast replication fails on some of the EFPs.
Conditions: Occurs under the following conditions:
1. You configure a group of EFPs and map each EVC to a different bridge-domain.
2. You create a QoS policy-map on each EVC.
3. All BDI send IGMP joins to single multicast group.
4. The router initiates multicast data traffic
5. You remove and reconfigure some of the EFPs
Workaround: Configure the EFPs and bridge-domains and initiate traffic flow before attaching
QoS policies.
• CSCua03439
Symptoms: The router displays error messages similar to the following:
