Command History This table includes the following release-specific history entries:
Usage Guidelines If external fragmentation exists in the L2TP environment, you must configure a quick-forwarding-ignore
traffic rule that bypasses all IP traffic targeted to either the LNS or LAC IP address. (See "Configuring
Traffic Rules and Counters” in the Cisco SCE8000 10GBE Software Configuration Guide or
“Configuring Traffic Rules and Counters” in the Cisco SCE8000 GBE Software Configuration Guide.)
This rule ensures that any packets not having the L2TP port indication (that is, non-first fragments) will
not require handling by the traffic processors.
In addition, to prevent reordering of L2TP tunneled fragments, you should define a quick-forwarding
traffic rule for all the L2TP traffic. This rule can be based on the IP ranges in use by the internal IPs in
the tunnel (as allocated by the LNS) or for all of the traffic passing through the Cisco SCE platform.
Note that flow redirection and flow blocking cannot be performed on the quick-forwarded traffic.
Authorization: admin
Examples The following example shows how to configure port 1000 as the L2TP port:
SCE8000>enable 10
Password:<cisco>
SCE8000#config
SCE8000(config)#interface linecard 0
SCE8000(config if)#l2tp identify-by port-number 1000
SCE8000(config if)#
port-number Port number to be configured for L2TP tunnels.
default port Replaces the user-configured port number with the default port number
(1701).
