[. . . ] (Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub. ) Default: Auto-negotiation enabled; Advertised capabilities for 100BASE-TX ­ 10half, 10full, 100half, 100full; 1000BASE-T ­ 10half, 10full, 100half, 100full, 1000full; 1000BASE-SX/LX/LH ­ 1000full) Note: Due to a hardware limitation, flow control only works on those ports located in the same chip (ports 1-24, 49 and ports 25-48, 50). · · Forced Mode ­ Indicates if a port or trunk has been set to forced mode. Trunk ­ Indicates if a port is a member of a trunk. To create trunks and select port members, see Chapter 26 "Multicast Configuration. " Note: Auto-negotiation must be disabled before you can configure or force the interface to use the Speed/Duplex Mode or Flow Control options. 17-12 © 2006 Foundry Networks, Inc. March 2006 Interface Commands USING THE CLI Use the commands in this section to configure interface settings from the CLI. interface Use this command to configure an interface type and enter interface configuration mode. Syntax interface interface no interface port-channel channel-id interface · ethernet unit/port - unit - This is device 1. · port-channel channel-id (Range: 1-6) · vlan vlan-id (Range: 1-4094) Default Setting None Command Mode Global Configuration Example To specify the Ethernet port, enter the following command: Console(config)#interface ethernet 1/25 Console(config-if)# channel-group Use this command to add a port to a trunk. Use the no form to remove a port from a trunk. Syntax channel-group channel-id no channel-group channel-id - Trunk index (Range: 1-6) Default Setting A new trunk contains no ports. Command Mode Interface Configuration (Ethernet) Command Usage · Static trunks have to be manually configured at both ends of the link. · Use no channel-group to remove a port group from a trunk. March 2006 © 2006 Foundry Networks, Inc. 17-13 Foundry EdgeIron User Guide · Use no interfaces port-channel to remove a trunk from the switch. The auto-negotiation behavior is dependent on a port's capability setting. Default Setting · 100BASE-TX: 10half, 10full, 100half, 100full · 1000BASE-T: 10half, 10full, 100half, 100full, 1000full · 1000BASE-SX/LX/LH: 1000full 17-16 © 2006 Foundry Networks, Inc. March 2006 Interface Commands Command Mode Interface Configuration (Ethernet, Port Channel) Command Usage When auto-negotiation is enabled with the negotiation command, the switch will negotiate the best settings for a link based on the capabilities command. When auto-negotiation is disabled, you must manually specify the link attributes with the speed-duplex and flowcontrol commands. Example The following example configures Ethernet port 5 capabilities to 100half, 100full and flow control. Console(config)#interface ethernet 1/5 Console(config-if)#capabilities 100half Console(config-if)#capabilities 100full Console(config-if)#capabilities flowcontrol Console(config-if)# Related Commands speed-duplex (17-14) negotiation (17-15) flowcontrol (17-17) flowcontrol Use this command to enable flow control. Use the no form to disable flow control. Syntax flowcontrol no flowcontrol Default Setting Flow control enabled Command Mode Interface Configuration (Ethernet, Port Channel) Command Usage · Flow control can eliminate frame loss by "blocking" traffic from end stations or segments connected directly to the switch when its buffers fill. When enabled, back pressure is used for halfduplex operation and IEEE 802. 3x for full-duplex operation. · When using the negotiation command to enable auto-negotiation, the optimal settings will be determined by the capabilities command. To enable flow control under auto-negotiation, "flowcontrol" must be included in the capabilities list for any port. · To force flow control on or off (with the flowcontrol or no flowcontrol command), use the no negotiation command to disable auto-negotiation on the selected interface. · Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. [. . . ] Rapid Spanning Tree Protocol (RSTP) RSTP reduces the convergence time for network topology changes to about 10% of that required by the older IEEE 802. 1D STP standard. March 2006 © 2006 Foundry Networks, Inc. Glossary-5 Foundry EdgeIron User Guide Remote Authentication Dial-in User Service (RADIUS) RADIUS is a logon authentication protocol that uses software running on a central server to control access to RADIUS-compliant devices on the network. Remote Monitoring (RMON) RMON provides comprehensive network monitoring capabilities. It eliminates the polling required in standard SNMP, and can set alarms on a variety of traffic conditions, including specific error types. Routing Information Protocol (RIP) The RIP protocol seeks to find the shortest route to another device by minimizing the distance-vector, or hop count, which serves as a rough estimate of transmission cost.
