Configuring the Media Type on Dual-Purpose Uplink Ports (CLI Procedure)
EX2200-C switches and ACX1000 routers provide two dual-purpose uplink ports. Each dual uplink port is a single interface that offers a choice of two connections: an RJ-45 connection for a copper Ethernet cable and an SFP connection for a fiber-optic Ethernet cable. You can choose to use either connection, but only one connection can be active at a time.
By default, if you plug a transceiver into the SFP connector, the port becomes a fiber-optic Gigabit Ethernet port, even if a copper Ethernet cable is plugged into the RJ-45 connection as well. If a transceiver is not plugged into the SFP connector, the port defaults to a copper 10/100/1000 Ethernet port.
You can constrain the use of the port to one connection type by configuring the media type for the port to be either copper or fiber. When you configure a media type on the port, the port will no longer accept the alternate connection type. For example, if you configure the uplink port as a fiber port and then plug a copper Ethernet cable into the RJ-45 connector, the interface will not come up.
To configure the media type for an uplink port:
user@switch# set interfaces interface-name media-type (Dual-Purpose Uplink Ports) media-type
For example, to set the media type for uplink port ge-0/1/0 to copper:
user@switch# set interfaces ge-0/1/0 media-type copper
 | Note: When you change the media type setting for a dual-purpose uplink port, it can take up to 6 seconds for the interface to appear in operational commands. |
