Monitoring and Managing Your ELS100-16TX

LCM displays the current IP address table, for example:

Port IP Address		Address Mask	MAC Address
1	192.138.217.1	255.255.255.0	00:40:27:00:06:1f
2	0.0.0.0	255.0.0.0	00:40:27:00:06:c3
3	192.138.217.10	255.255.255.0	00:40:27:00:06:3e
4	0.0.0.0	255.0.0.0	00:40:27:00:03:7a
5	0.0.0.0	255.0.0.0	00:40:27:00:05:c7
6	192.138.217.20	255.255.255.0	00:40:27:00:04:4a
7	192.138.217.50	255.255.255.0	00:40:27:00:06:9e

To change the subnet mask, at the LCM prompt:

1.Type ipaddr <PORT-NUMBER> <IP ADDRESS> <SUBNET MASK>

For example, ipaddr 6 192.138.217.40 255.255.240.0 would set the subnet mask for port 6 to 255.255.240.0. LCM responds by redisplaying the address table.

Note: When you change the subnet mask for a port, you must also enter the IP address for that port. Make sure you enter the IP address for the port correctly; whatever you enter becomes the IP address.

To assign a new IP address, refer to Section 3.1.

4.5.4 Changing a Community Name

A community name is similar to a password. You use the same steps to assign a new community name or to change an existing community name. This sets the MIB variable sxadminAnyPass. You can then enter a community name to perform any SNMP sets.

To assign a community name, at the LCM prompt:

1.Type community

2.Enter the old community name.

If one has not been assigned, you do not need to enter anything. LCM prompts you for the new community name.
