30 Router Card (WS-X3011) Conﬁguration Note

Conﬁgure the IP address and subnet mask for the LAN interface:

Router (config)# interface type port_number

Router (config-if)# ip address ipaddress subnetmask

Conﬁgure the IP address and subnet mask for the BRI interface:

Router (config-if)# interface bri port_number

Router (config-if)# ip address ipaddress subnetmask

If you are using an ISDN switch type (such as Basic NI1 or DMS-100) that requires a

service proﬁle identiﬁer (SPID), enter the SPID and optional local directory number

(LDN). The SPID and LDN are assigned by the ISDN service provider.

The SPID is a number that identiﬁes the service to which you have subscribed. A SPID

is not required for AT&T 5ESS service conﬁgured for a point-to-point connection.

The LDN is an optional seven-digit phone number for the channel.

Router (config-if)# isdn spid1 SPID_no [LDN]

Router (config-if)# isdn spid2 SPID_no [LDN]

Conﬁgure the router for PPP encapsulation and CHAP authentication:

Router (config-if)# encapsulation ppp

Router (config-if)# ppp authentication chap

Enter the load-threshold or ppp multilink command to set up a second B channel.

For bandwidth on demand, enter the load-threshold command to set the ISDN load

threshold. The load threshold determines the percentage of network load at which the

second ISDN B channel is activated. The value ranges from 1 to 255 (100 percent). In the

following example, the value of 128 means that when the ﬁrst B channel reaches

50 percent of its bandwidth capacity (128 equals 50 percent of 255), the second B channel

will activate to assist with the bandwidth load:

Router (config-if)# dialer load-threshold 128

Alternatively, you can use Multilink PPP to activate a second ISDN line. For Multilink

PPP to work, the router must be running Cisco IOS Release 11.0(3) or a later release, and

both the current router and target router must support Multilink PPP:

Router (config-if)# ppp multilink

Enter the dialer map command to provide the information necessary to successfully

route packets to the target router. Do not use periods or hyphens when entering the

number to dial:

Router (config-if)# dialer map protocol targetBRIport_ipaddress name

targetrouter_number

Enter the dialer-group command to specify the number of the group permitted to access

the router:

Router (config-if)# dialer-group groupnumber

Enter the exit command to exit interface conﬁguration mode.

Enter the dialer list command to specify the groups and protocols permitted to access the

router:

Router (config)# dialer-list groupnumber protocol protocol_type permit
