Out-of-Band Management port

The Out-of-Band Management (OoBM) port, enabled by default, is intended to provide a means to access and manage the switch from a network segregated from production traffic. Only stations on the segregated management network can gain management access to the switch; this sharply limits the universe of devices that may attempt unauthorized access.

Switch management services can be configured to use the OoBM port rather than switch data ports. Traffic cannot be routed between the OoBM port and data ports, and the OoBM port can be assigned a dedicated gateway address. In a switch stack (backplane or VSF), a single global OoBM IP address can be assigned for the entire stack, in addition to addresses for each individual stack member.

This example sets a global OoBM IP address on a three-switch stack, as well as individual static addresses for each of the three members:

switch(config)# oobm
switch(oobm)# ip address 10.1.0.5/24
switch(oobm)# ip default-gateway 10.1.0.1
switch(oobm)# member 1
switch(oobm member-1)# ip address 10.1.0.6/24
switch(oobm member-1)# ip default-gateway 10.1.0.1
switch(oobm member-1)# member 2
switch(oobm member-2)# ip address 10.1.0.7/24
switch(oobm member-2)# ip default-gateway 10.1.0.1
switch(oobm member-2)# member 3
switch(oobm member-3)# ip address 10.1.0.8/24
switch(oobm member-3)# ip default-gateway 10.1.0.1

To use DHCP on a standalone switch:

switch(config)# oobm
switch(oobm)# ip address dhcp-bootp

There are a couple of useful show commands that can be used to monitor the status of OoBM ports:

switch# show oobm
