Configuring Ports
Configuration Expert lets you enable and disable ports as well as configure the following
characteristics:
• Operating mode (half-duplex or full-duplex).
In half-duplex mode, a port can transmit data in only one direction at a time between
two stations.
In full-duplex mode, a port can simultaneously send and receive data.
• Port speed (10-Mbps or 100-Mbps). This parameter applies only to ports on the
10/100 modules.
• Auto negotiation (for Gigabit Ethernet ports)
• Hash mode, which controls the distribution of flow entries in Layer-2 and Layer-3
lookup tables. (For more information on hash modes, see
“Configuring Global Settings
on All Ports” on page 52 .)
Note:
Cabletron has configured the SSR’s hash mode to its optimal setting. It is
recommended you not change the hash mode unless advised to do so by
Cabletron Technical Support.
You can configure global settings for all SSR ports as well as configure individual ports. If
most of an SSR’s ports are to be configured with the same or similar settings, you can first
apply global settings to all ports and then modify those settings on individual ports as
needed. Separate discussions on configuring default settings for all ports and configuring
an individual port follow.
Configuring Global Settings on All Ports
To configure global settings on all of the SSR’s ports:
1. Start Configuration Expert if you have not already done so.
2. Open the configuration file you want to modify and then double-click that file’s
System Configuration object.
3. Double-click the Chassis Configuration object.
4. Click the Global Port Parameters object.
A Global Attributes of Ports dialog box similar to the following appears:
