Cabletron Systems 100 manual NoRIP Option, Changing a Subnet Mask

Monitoring and Managing Your ELS100-16TX

For example, enable 7-9would enable ports 7, 8, and 9.

LCM responds:

Port 7: Enabled, Rip listening

Port 8: Enabled, Rip listening

Port 9: Enabled, Rip listening

Note: Rip listening means that the ELS100-16TX is in listening mode only. No RIP packets are created.

noRIP Option

The Routing Information Protocol (RIP) is one of the protocols that allows the ELS100-16TX to build an accurate, current routing table. This table includes the networks it knows about, the next hop, and the number of hops to get there. RIP enables you to use an NMS to remotely manage the ELS100-16TX through a router.

The noRIP option allows you to turn off the routing information that builds the routing table. You would use this option when you are connecting network devices that do not support RIP.

4.5.3 Changing a Subnet Mask

You can optionally set the subnet mask for a port. A subnet mask is a 32-bit address mask used in IP to specify a particular subnet. If the subnet mask is 0.0.0.0, the ELS100-16TX automatically converts the displayed mask to the standard default, based on the port’s IP address class. (Class A address masks are 255.0.0.0, Class B address masks are 255.255.0.0, Class C address masks are 255.255.255.0.)

To display IP addresses, subnet masks, and MAC addresses of all ports on the ELS100-16TX you are managing, at the LCM prompt:
