Enter exit while in global configuration mode to return to privileged EXEC node. device(config)# exit device# 6. To verify the new host name, you can run the show running-config command in EXEC mode.
Setting the date and time Time zones You can set the time zone for a device by using the clock timezone command. The time zone setting has the following characteristics: • The time zone setting automatically adjusts for Daylight Savings Time. • Changing the time zone on a device updates the local time zone setup and is reflected in local time calculations. • By default, all devices are in the Greenwich Mean Time (GMT) time zone (0,0).
Changing the RBridge ID and VCS ID Setting the time zone You must perform this procedure on all devices for which the time zone must be set. However, you only need to set the time zone once on each device, because the value is written to nonvolatile memory. While not necessary for device operation, setting a time zone is part of ensuring accurate logging and audit tracking. Time zone changes persist through a reboot without having to save the current running configuration.
Configuring operating modes on 27x40 GbE line cards For details on using these commands, refer to the Extreme Network OS Command Reference and Extreme Network OS Management Configuration Guide. Configuring operating modes on 27x40 GbE line cards You can configure Performance or Density mode for the port groups on the 27x40 GbE line card . When configured in Performance mode, the third port in the group is persistently disabled, allowing the remaining two ports to operate at up to 40 Gbps.
Backing up a running configuration 8. Exit hardware configuration mode. device(config-hardware)# exit 9. Exit global configuration mode. device(config)# exit device# 10. Power on the line card. device# power-on linecard 3 Displaying operating modes To display the current operating mode for a specific port group, use the show running-config hardware port-group command with the rbridge-id/slot-id/port group-id parameters.
Connecting network devices Connecting network devices You can connect your chassis to a variety of network devices. Refer to the following topics for some specific requirements for making these connections. Connecting to Ethernet devices For copper connections to a 10/100Base-TX or 1000Base-T device or another Extreme Networks device, a crossover cable is required. NOTE The 802.3ab standard (automatic MDI or MDIX detection) calls for automatic negotiation of the connection between two 1000Base-T ports.
Installing transceivers and attaching cables Installing SFP and SFP+ transceivers and cables Complete the following steps to install optical SFP and SFP+ transceivers. 1. Add the transceivers and cables to the line card ports. Position one of the optical transceivers so that the key is oriented correctly to the port. Insert the transceiver into the port until it is firmly seated and the latching mechanism clicks. Transceivers are keyed so that they can only be inserted with the correct orientation.
Managing cables Managing cables Cables can be organized and managed in a variety of ways; for example, using cable channels on the port sides of the rack or patch panels to minimize cable management. The cable management comb is located above the modules on the port side of the chassis. Extreme Networks recommends the following best practices for cable management. • Leave at least 1 m (3.28 ft.) of slack for each port cable.
