Port Mode Port LED Color Description
LRE
Note In LRE mode, the LRE port LEDs show the LRE link status between the LRE switch and the connected
CPE. To display additional information about the LRE links, use the Port Settings window or the show
controllers lre privileged EXEC commands. This mode does not apply to the 10/100 switch ports,
which continue to show Ethernet link status as described in Table 2-7.
Cyan (off) No LRE link present on the LRE port.
Green LRE link present on the LRE port. Port LED turns green in approximately 10 seconds
after the LRE port detects a connection to a CPE.
Amber Switch LRE port and CPE RJ-11 wall port unable to establish the rate defined by the
assigned profile.
STAT
Note STAT mode on the LRE switch shows the status of the CPE Ethernet link between a Cisco 575 LRE
CPE and a remote Ethernet device, such as a PC. This mode does not apply to connected Cisco 585 LRE
CPEs.
2
This mode is different for the switch 10/100 ports, as described in Table 2-7.
Cyan (off) No link present on the CPE Ethernet port.
Green CPE Ethernet link present between the CPE Ethernet port and the remote Ethernet
device. CPE Ethernet port is in STP forwarding state.
Amber Link fault. Error frames can affect connectivity, and errors such as excessive collisions,
CRC errors, and alignment and jabber errors are monitored for a link-fault indication.
CPE Ethernet port is not forwarding. Port was disabled by management, by an address
violation, or was blocked by STP.
Note After a port is reconfigured, the port LED can remain amber for up to
30 seconds as STP checks the switch for possible loops.
Brown No link, and the CPE Ethernet port is administratively shut down.
2
DUPLX Note DUPLX mode on the LRE switch shows the duplex mode of the Ethernet port on a Cisco 575 LRE CPE.
This mode does not apply to Cisco 585 LRE CPEs.
2
This mode is different for the switch 10/100 ports,
as described in Table 2-7.
Cyan (off) CPE Ethernet port is operating in half-duplex mode.
Green CPE Ethernet port is operating in full-duplex mode.
SPEED
Note SPEED mode on the LRE switch shows the speed of the Ethernet port on a Cisco 575 LRE CPE. This
mode does not apply to Cisco 585 LRE CPEs.
2
This mode does not show the LRE link speed, which is
displayed from the Port Settings window or show controllers lre privileged EXEC commands. This
mode is different for the switch 10/100 ports, as described in Table 2-7.
Cyan (off) CPE Ethernet port is operating at 10 Mbps.
Green CPE Ethernet port is operating at 100 Mbps.
1. This table describes the LRE port LEDs. See Table 2-7 for information on the 10/100 port LEDs on the LRE switch.
2. The LRE switch does not show the CPE Ethernet link status, duplex, or speed of the Ethernet ports on the Cisco 585 LRE CPEs. The LEDs for the switch
LRE ports connected to these CPEs are cyan in this mode. To display the status of these CPEs, use the show remote interfaces status user EXEC
command.
