OL-10394-05 Rev. R0

Summary: Cisco’s VTP protocol implementation in some versions of Cisco IOS and CatOS may be
vulnerable to a DoS attack via a specially crafted VTP packet sent from the local network segment
when operating in either server or client VTP mode. When the device receives the specially crafted
VTP packet, the switch may crash (and reload/hang). The crafted packet must be received on a
switch interface configured to operate as a trunk port.
Workarounds:There are no workarounds available for this vulnerability.

Symptoms: Link debounce down feature not working on RSP720-3C-10GE ports due to fast link
feature.
Conditions: Occurs when link debounce is configured on RSP720-3C-10GE.
Workaround: Use “carrier-delay” instead.
Further Problem Description: On configuring link debounce, fast link, which is enabled by default
and has no CLI, needs to go off but does not.

• CSCsv08528
Symptoms: After the Resilient Ethernet Protocol (REP) topology is returned by the rep preempt
command, MAC address table is not cleared.
Conditions: During internal testing, this occurred approximately 3 times out of 20.
Workaround: Use the clear mac-address-table dynamic command to clear the table.
• CSCsv13243
Symptoms: Configuring Bidirectional Forwarding Detection (BFD) for a Border Gateway Protocol
(BGP) neighbor that is established on a subinterface will cause the BGP session to go down.
Conditions: Occurs on a Cisco 7600 router with BGP session established on a subinterface and the
subinterface is configured in “native vlan” mode while the configured BFD session is in ECHO
Mode.
Workaround: Configure subinterface in “non-native” mode.
