cpe toggle
cpe toggle
Use the cpe toggle interface configuration command to enable the CPE toggle feature. When this feature
is enabled, a remote customer premises equipment (CPE) link automatically transitions from down to up
if the Long-Reach Ethernet (LRE) link comes up in less than 30 seconds. Use the no form of this
command to disable the CPE toggle feature on a specific port or on the switch.
cpe toggle [port cpe-port-id]
no cpe toggle [port cpe-port-id]
This command is available only on Catalyst 2950 Long-Reach Ethernet (LRE) switches.
Syntax Description
Defaults CPE toggle is enabled on all interfaces.
Command Modes Interface configuration
Command History
Usage Guidelines A CPE Ethernet link is the connection between the CPE Ethernet port and the remote Ethernet device
(such as a PC) connected to it. It is not the link between the switch LRE port and the LRE CPE device,
which is referred to as the LRE link.
CPE toggle cannot be disabled on a Cisco 575 LRE or Cisco 576 LRE 997 CPE link.
You can disable CPE toggle on a link from a Cisco 585 LRE CPE to a remote Ethernet device. You can
disable CPE toggle on all interfaces or on a specific interface by using the no cpe toggle [port
cpe-port-id] interface configuration command. If CPE toggle is disabled and the LRE link comes up in
less than 30 seconds, the CPE link transitions from down to up.
If the port keyword is not specified, this command applies to all Fast Ethernet ports on a CPE device. If
the port keyword and a port ID are specified, this command applies to the specific Fast Ethernet port on
the CPE and overrides the global configuration.
Examples This example shows how to disable CPE toggle on a CPE port:
Switch# configure terminal
Switch(config)# interface longreachethernet0/2
Switch(config-if)# no cpe toggle
port cpe-port-id (Optional) The CPE port identifier. The range is 1 to 4.
