- Specifies the port to break out certain 40 Gbps ports into four 10 Gbps sub-ports for ICX 7750 devices and 40/100 Gbps ports into four 10/25 Gbps sub-ports for ICX 7850 devicesrespectively. If there are two port identifiers in the command line, the first port designates the beginning port in a range of ports to be broken out, and the second port indicates the end of the breakout range. When a range is specified, the 10 Gbps sub-ports within the range are implicitly included.
Global configuration mode
Use the
no form of the command to remove breakout configuration from the designated port or
range of ports.
No configuration may be present on a port for which the
breakout ethernet command is issued. When the command is issued on a port with pre-existing configuration,
an error message is returned. The existing configuration must be removed before the
breakout ethernet command is re-issued.
The breakout ethernet command is available only on certain ICX 7850 40 Gbps ports and 100 Gbps ports. Refer
to the
FastIron Ethernet Switch Administration Guide for a table of available breakout ports. Refer to the
ICX 7850 Ethernet Switch Hardware Installation Guide for detailed information on breakout cables.
The
breakout ethernet command can be issued on stand-alone units only. Stacking cannot be enabled on a
port configured for breakout. An error is returned if you try to enable stacking on
a unit that has any breakout ports configured. The breakout configuration must be
removed manually before stacking can be enabled. Use the
show breakout command to display the breakout configuration for a unit.
The
breakout ethernet and
no breakout ethernet commands must be followed by a
write memory command and a
reload command for the port configuration changes to take effect.
The following example configures breakout on port 1/1/5, after existing configuration on the port is removed.
Device# configure terminal Device(config)# breakout ethernet 1/1/5 Error: Port 1/1/5 has sflow forwarding Device(config)# interface ethernet 1/1/5 Device(config-if-e40000-1/1/5)# no sflow forwarding Device(config-if-e40000-1/1/5)# end Device# write memory Write startup-config done. Device# configure terminal Device(config)# breakout ethernet 1/1/5 Reload required. Please write memory and then reload or power cycle. Device(config)# write memory Write startup-config done. Device(config)# Flash Memory Write (8192 bytes per dot) . Copy Done. Device(config)# end Device# reload
The following example checks for ports with active breakout configuration and then removes breakout from ports 1/3/1 through 1/3/6.
