ADC SG-1 user manual Setting multi-link mode, Hostconfig# multilink-mode, Defining an address pool

Chapter 7: Second Level Commands June 30, 2006

<mask>

The mask of the network allowed connecting the LNS.

<alpha-numeric string>

Password used for authenticating between LAC and LNS.

Example(s)

Host(config)# tunnel-server host 12.25.3.15 mask 255.255.255.0 password rewed

Setting multi-link mode

Host(config)# multilink-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

Host(config)# ip local-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>
