Switched 56 Wide Area Network (WAN) LinkThe following example show how to set up two routers to dial each other on demand via switched 56k Point to Point Protocol (PPP) connection. Wide Area Network( WAN) port on router 'A' called field4-gw (144.52.116.4) to
dial on demand via switched 56K to router 'B' called oh-gw (144.52.164.1) and
vice versa. The default gateway for router 'A' field4-gw to the rest of the
corporate net is 144.52.116.2. Note: Only use the commands for Signaling Network
Management Protocol (SNMP) >set snmp if this protocol will be used on the
router, otherwise it is not required. Step 1 Command> set address 144.52.116.4 Command> set gateway 144.52.116.2 Command> set sysname field4-gw Command> set snmp on Command> set snmp readcommunity public Command> add snmphost reader any Command> add snmphost writer none Command> set s2 network twoway Command> set s2 group 2 Command> set s2 modem on Command> set s2 protocol ppp Command> save s2 Command> reset s2 Command> add netuser oh-gw # must be the SNMP sysname of remote system Command> set user oh-gw protocol ppp Command> set user oh-gw mtu 1500 Command> set user oh-gw address 144.52.164.1 Command> set user oh-gw netmask 255.255.255.0 Command> set user oh-gw routing on Command> set user oh-gw password what3ever Command> add location oh-gw # set up location so field4-gw can Command> dial out to oh-gw Command> set oh-gw manual Command> set oh-gw addr 144.52.164.1 Command> set oh-gw netmask 255.255.255.0 Command> set oh-gw routing on Command> set oh-gw protocol ppp Command> set oh-gw mtu 1500 Command> set oh-gw idletime 5 # drop connection after 5 minutes idle Command> set oh-gw maxports 1 Command> set oh-gw high_water 0 # 0 unless maxports > 1 Command> set oh-gw group 2 # dial group, also set on ports to match the location table # replace 7005551234 with the telephone number of oh-gw Command> set oh-gw tele 17005551234 Command> save all Step 2 Command> set address 144.52.164.1 Command> set gateway 144.52.116.4 Command> set sysname oh-gw Command> set snmp on Command> set snmp readcommunity public Command> add snmphost reader any Command> add snmphost writer none Command> set s1 network twoway Command> set s1 group 0 Command> set s1 modem on Command> set s1 protocol ppp Command> save s1 Command> reset s1 Command> add netuser field4-gw Command> set user field4-gw protocol ppp Command> set user field4-gw mtu 1500 Command> set user field4-gw address 144.52.116.4 Command> set user field4-gw netmask 255.255.255.0 Command> set user field4-gw routing on Command> set user field4-gw password what3ever Comand> add location field4-gw # set up location so oh-gw can dial out to field4-gw Command> set field4-gw manual Command> set field4-gw addr 144.52.116.4 Command> set field4-gw netmask 255.255.255.0 Command> set field4-gw routing on Command> set field4-gw protocol ppp Command> set field4-gw mtu 1500 Command> set field4-gw idletime 5 # drop connection after 5 minutes idle Command> set field4-gw maxports 1 Command> set field4-gw high_water 0 # 0 unless maxports > 1 Command> set field4-gw group 0 # dial group, also set on ports to match location table # replace 7005551234 with the telphone number of field4-gw Command> set field4-gw tele 17005551234 Command> save all Step 3 Command> dial oh-gw -x If attempt is successful, RESET THE PORT and change it from manual to on_demand, as follows: Command> reset s2 Command> set oh-gw on_demand Command> save all If attempt is unsuccessful, set a debug to capture PPP negotiations and dial out again as shown in step 3. Command> set console Command> set debug 0x51 Step 4 Command> reset s1 Command> set field4-gw on_demand Command> save all |
