7-42 SG1-UM-8500-03
<mask>
The mask of the network allowed connecting the LNS.
<alpha-numeric string>
Password used for authenticating between LAC and LNS.
Example(s)
Setting multi-link mode
The SG-1 allows the user to use higher bandwidth by using ML-PPP. Typically ML-PPP is used to combine the
speed of a few ISDN BRI B-Channels to get 128 Kbps or other N x 64 Kbps of virtual bandwidth, depending on the
RADIUS database and the SG-1 configuration.
Usage
multilink-mode <multi-cage | single-cage | none>
Parameter(s)
This command has the following options:
•multi-cage–ML-PPP uses PPP projection to call master method. The port limit is received from the RADIUS.
If no port limit is defined, the system default is 1 (according to the RFC). This means 64 Kbps is the maximum
bandwidth (none mode behavior). This is for a scenario of various SG-1SCC cards in a POP.
•single-cage–ML-PPP uses PPP projection to call master method. The port limit is received from the RADIUS.
If no port limit is defined, the system default is 1 (according to the RFC). This means 64 Kbps is the maximum
bandwidth (none mode behavior). The difference with the Multi-Cage option is the efficiency of the bundling
(in this scenario there is only one SCC card).
•none–no Multi link operation is allowed in the SG-1. All the PPP links port limit definitions are 1. This means
the MLP protocol negotiation is allowed (MLP user), but only one link is available.
Defining an address pool
The ip local pool command allows you to define IP pools for all the incoming sessions. There are three required
command line arguments-the pool name, the starting IP address in the pool, and the last IP address in the pool.
Usage
ip local-pool <pool_name> <starting_IP> <last_IP> <internal | external>
Host(config)# tunnel-server host 12.25.3.15 mask 255.255.255.0 password rewed
Host(config)# multilink-mode
Host(config)# ip local-pool
