4. Configure the serial interface settings.
SN(cfg)#port serial 0 0
SN(prt-ser)[0/0]#shutdown
SN(prt-ser)[0/0]#encapsulation framerelay
SN(prt-ser)[0/0]#hardware-port x21
SN(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.
SN(prt-ser)[0/0]#framerelay
SN(frm-rel)[0/0]#lmi-type ansi
SN(frm-rel)[0/0]#keepalive 20
SN(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.
SN(frm-rel)[0/0]#pvc 1
SN(pvc)[1]#encapsulation rfc1490
SN(pvc)[1]#fragment 300
SN(pvc)[1]#bind interface external router
SN(pvc)[1]#no shutdown
SN(pvc)[1]#pvc 2
SN(pvc)[2]#encapsulation rfc1490
SN(pvc)[2]#bind interface internal router
SN(pvc)[2]#no shutdown
7. Check that the Frame Relay settings are correct.
SN(frm-rel)[0/0]#show framerelay
