Configuring The Keep-Alive Interval; Enabling Fragmentation - Patton electronics SmartWare R.3.20 Software Configuration Manual

SmartWare Software Configuration Guide
Mode: Frame Relay
Step
node (frm-rel)[ slot/port ]#lmi-type {ansi | gof | itu} Sets the LMI type
1
Example: Configuring the LMI type
The following example sets the LMI type to ANSI T1.617 Annex D for Frame Relay over the serial interface
on slot 0 and port 0.
node(cfg)#port serial 0 0
node(prt-ser)[0/0]#framerelay
node(frm-rel)[0/0]#lmi-type ansi
Configuring the keep-alive interval
A keep-alive interval must be set to configure the LMI. By default, this interval is 10 seconds and, according to
the LMI protocol, must be less than the corresponding interval on the switch. The keep-alive interval in sec-
onds, which is represented by number, has to be in the range from 1 to 3600.
This procedure describes how to set the keep-alive interval
Mode: Frame Relay
Step
node (frm-rel)[ slot/port ]#keepalive number
1
To disable keep-alives on networks that do not utilize LMI, use the
configuration command.
Example: Configuring the keep-alive interval
The following example sets the keepalive interval to 10 seconds for Frame Relay over the serial interface on slot
0 and port 0.
node(cfg)#port serial 0 0
node(prt-ser)[0/0]#framerelay
node(frm-rel)[0/0]#keepalive 10

Enabling fragmentation

FRF.12 interface and end-to-end fragmentation of large IP packets is supported to reduce the delay imposed
on voice packets on slow links (less than 512 kbps). As opposed to IP fragmentation, Frame Relay fragmenta-
tion is transparent to the IP layer. This leaves IP packets unchanged, which may be important for IP-based
applications susceptible to IP fragmentation.
