136 Serial Port Configuration
Software Configuration Guide Release 2.10, Revision 1.00
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 of a SmartNode 2300 series device.
SN(cfg)# port serial 0 0
SN(prt-ser)[0/0]# framerelay
SN(frm-rel)[0/0]# lmi-type ansi
16.10 Configuring the Keepalive Interval
A keepalive 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
keepalive interval in seconds, which is represented by
number , has to be in the range from 1 to 3600.
Procedure
To set the keepalive interval
Mode
Frame Relay
Command Purpose
Step 1 node (frm-rel)[ slot / port ]#keepalive number Sets the LMI keepalive interval
To disable keepalives on networks that do not utilize LMI, use the
no keepalive interface
configuration command.
Example: Configuring the Keepalive Interval
The following example sets the keepalive interval to 10 seconds for Frame Relay over the serial
interface on slot 0 and port 0 of a SmartNode 2300 series device.
SN(cfg)# port serial 0 0
SN(prt-ser)[0/0]# framerelay
SN(frm-rel)[0/0]# keepalive 10
16.11 Enabling Fragmentation
SmartWare supports FRF.12 interface and end-to-end fragmentation of large IP packets to reduce the
delay imposed on voice packets on slow links (<512kBit/s). As opposed to IP fragmentation (also
supported by SmartWare) Frame Relay fragmentation is transparent to the IP layer thus leaving IP
packets unchanged which may be important for IP based applications susceptible to IP
fragmentation.
Procedure
To enable Frame Relay fragmentation
Mode
Frame Relay
Command Purpose
Step 1
node (cfg)#port serial slot port
Selects the serial interface on slot and
port.
Step 2 node (prt-ser)[ 0/0 ]#framerelay Enter Frame Relay configuration mode.
