Frame Relay configuration task list

SmartWare Software Configuration Guide 

4. Configure the serial interface settings.

node(cfg)#port serial 0 0
node(prt-ser)[0/0]#shutdown
node(prt-ser)[0/0]#encapsulation framerelay
node(prt-ser)[0/0]#hardware-port x21
node(prt-ser)[0/0]#port-type dte
…

5. Configure the Frame Relay. You must thus change to the Frame Relay configuration mode. Use the ser-

vice-policy profile defined above to give voice priority over data.

node(prt-ser)[0/0]#framerelay
node(frm-rel)[0/0]#lmi-type ansi
node(frm-rel)[0/0]#keepalive 20
node(frm-rel)[0/0]#use profile service-policy VoicePrio out
…

6. Configure the introduced PVCs. Enable fragmentation for PVC 1. The voice uses codec G.723 at a packet 

size of 30ms, so the minimum fragment size must be 66 Bytes. Setting the fragment size to 300 (Bytes) 
introduces an additional delay of at most 4.7ms (300 * 8/512k) but does not cause too much fragmenta-
tion overhead on large data packets.

node(frm-rel)[0/0]#pvc 1
node(pvc)[1]#encapsulation rfc1490
node(pvc)[1]#fragment 300
node(pvc)[1]#bind interface external router
node(pvc)[1]#no shutdown
node(pvc)[1]#pvc 2
node(pvc)[2]#encapsulation rfc1490
node(pvc)[2]#bind interface internal router
node(pvc)[2]#no shutdown
…

7. Check that the Frame Relay settings are correct.

node(frm-rel)[0/0]#show framerelay
