Cisco Cisco IOS Software Releases 12.2 MC

Note that these limits are on a “per-link” basis. For example, issuing ppp multilink slippage mru 4 
means that the total amount of data which is buffered by the bundle is 4 times the MRU times the number 
of links in the bundle.

The reassembly engine is also affected by the lost fragment timeout, which is configured using the 
ppp timeout multilink lost-fragment command.

The buffer limit derived from the slippage constraints implies a corresponding tolerated differential 
delay between the links. Since it does not make sense to be declaring a fragment lost due to a timeout 
when it is within the delay window defined by the slippage, the timeout will be dynamically increased 
as necessary so that it is never smaller than the delay value derived from the slippage parameters.

 

This section contains information that was not included or was documented incorrectly in the 
MGX-RPM-1FE-CP Back Card Installation and Configuration Note. The heading in this section 
corresponds with the applicable section title in the documentation.

The maximum number of RTP header compression connections is documented as 150 per T1 interface 
and up to 600 connections per MLP bundle when in fact, 1000 connections are supported per MLP 
bundle regardless of whether the bundle contains one T1 interface or four.

The efficiency improvement factor calculation documented in the show ppp mux command section is 
incorrect. The correct improvement factor calculation uses bytes, not packets, and is as follows:

Multiplex efficiency improvement factor = 100 * (Total bytes saved) / (Total bytes received)

Where total bytes saved = bytes_received_at_muxer - bytes_sent_at_muxer.

Demultiplex efficiency improvement factor = 100 * (Total bytes saved) / (Total bytes sent)

Where total bytes saved = bytes_sent_at_demuxer - bytes_received_at_demuxer.

The detail keyword is not supported in the show ip rtp header-compression command on the 
MGX-RPM-1FE-CP back card. Output does not display for the 

 keyword if specified in 

command.

The following sections describe the available documentation related to the Cisco MGX-RPM-1FE-CP 
back card.These documents consist of hardware and software installation guides, Cisco IOS 
configuration guides and command references, system error messages, and other documents.

Documentation is available in printed or electronic form.
