Cisco Cisco IOS Software Releases 12.2 MC Notas de publicación

To configure the cUDP flow expiration timeout duration, issue the following command while in 
multilink interface configuration mode:

To restore the default, use the no form of this command. 

This new feature is identified by CSCeb44623.

When working with a MGX-RPM-1FE-CP back card, please take note of the following limitations, 
restrictions, and important notes:

FastEthernet and multilink interfaces should be shut down before online insertion and removal 
(OIR) of the MGX-RPM-1FE-CP.

The MGX-RPM-1FE-CP is only supported on the Cisco MGX 8850 RPM-PR.

For PPP Multiplexing, MLP must be configured on the MGX-RPM-1FE-CP back card.

For error messages to be stored, console logging must be configured.

The IP MTU should be set to 512 bytes or less on multilink interfaces.

The MGX-RPM-1FE-CP back card supports up to 16 multilink interfaces.

MLP with LFI is not supported by the Cisco MWR 1941-DC router. Therefore, MLP with LFI must 
be disabled on peer devices connecting to the Cisco MWR 1941-DC router T1 MLP connections.

To fully disable PPP Multiplexing, issue the no ppp mux command on the T1 interfaces of the 
routers at both ends of the T1 link. If PPP Multiplexing remains configured on one side of the link, 
that side will offer to receive PPP multiplexed packets.

If upgrading to Cisco IOS Release 12.2(8)MC2c or later for the ACFC and PFC support on PPP 
interfaces, ensure that you upgrade the MGX-RPM-1FE-CP backcard image first. After doing so, 
immediately upgrade all MWR 1941-DC routers connected to the MGX-RPM-1FE-CP back card.

The following sections list and describe the open and resolved caveats for the Cisco MGX-RPM-1FE-CP 
with Cisco IOS Release 12.2(15)MC2c. Only severity 1 through 3 caveats are included.

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most 
serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these 
three severity levels.

Caveats in Cisco IOS Releases 12.2 and 12.2 T are also in Cisco IOS Release 12.2(15)MC2c. For 
information on caveats in Cisco IOS Release 12.2, see Caveats for Cisco IOS Release 12.2. For 
information on caveats in Cisco IOS Release 12.2 T, see Caveats for Cisco IOS Release 12.2 T. These 
two documents list severity 1 and 2 caveats and are located on CCO and the Documentation DVD. 

Router(config-if)# ppp iphc max-time seconds

Specifies the duration of inactivity, in seconds, that when 
exceeded causes the cUDP flow to expire. The recommended 
value is 8.
