Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S
Conditions: This symptom is observed on a Cisco 10720 that runs Cisco IOS Release 12.0(24)S or
a later release when you send IPv4 traffic from a Fast Ethernet (FE) ingress interface to an FE egress
interface.
Workaround: There is no workaround.

Symptoms: In a redundancy configuration, a secondary Performance Routing Engine (PRE) may
continue to reload at startup and not complete its bootup process.
Conditions: This symptom is observed on a Cisco 10000 series when the switchover timeout
timeout-period redundancy configuration (main-cpu mode) command is configured, when you have
entered 0 for the timeout-period argument, and when the secondary PRE is reset.
To recover form the symptom, power cycle the router, or perform the following steps:
1. Remove the affected secondary PRE.
2. Reload the primary PRE.
3. When the Primary PRE has booted, deconfigure the switchover timeout timeout-period
redundancy configuration (main-cpu mode) command.
4. Reinstall the secondary PRE, which should bootup normally.
Workaround: Do not configure the switchover timeout 0 redundancy configuration (main-cpu
mode) command. Note that the symptom occurs only when you have entered 0 for the
timeout-period argument, not when you have entered other values.

Symptoms: The neighbor ip-address send-label address family configuration command may not
function properly for an IP version 6 (IPv6) Border Gateway Control (BGP) neighbor that is part of
a BGP peer group in an IPv6 address family; the functionality of the send-label keyword may not
be advertised to the peers.
Conditions: This symptom is observed when you use BGP peer groups with a provider edge (PE)
router that is running IPv6 in a Multiprotocol Label Switching (MPLS) environment (referred to as
a 6PE router).
Workaround: Enter the neighbor ip-address send-label address family configuration command for
the IPv6 BGP neighbor before you make the IPv6 BGP neighbor part of the BGP peer group in the
IPv6 address family.

Symptoms: When you configure a Cisco 10000 series, messages similar to the following ones may
appear, and a VLAN may not be enabled:

Conditions: This symptom is observed on a Cisco 10000 series when you change the encapsulation
of a LAN subinterface to dot1q encapsulation while the subinterface is shut down.
