Returning to Multiple MAC Router Mode
You cannot re-enable multiple MAC router mode via the CLI
. In order to return the switch to this default
setting, you must add the following command syntax to the
boot.cfg
file:
vlan router mac multiple enable
After adding the command syntax to the
boot.cfg
file and saving your changes, reboot the switch.
When the switch boots, the system software reads from the
boot.cfg
file. All valid command syntax,
including
vlan router mac multiple enable
, is initialized and multiple MAC router mode is re-enabled.
Because the syntax has been added to the switch’s
boot.cfg
file, multiple MAC router mode will remain
enabled after subsequent switch reboots.
Viewing Current Multiple MAC Router Mode Status
To view the switch’s current MAC router mode status (i.e., whether multiple MAC router mode is enabled
or disabled), use the
show vlan router mac status
command. For example:
-> show vlan router mac status
router-mac-multiple total vlans router vlans ip vlans ipx vlans
----------------------+-------------+--------------+----------+------------
enabled 5 3 3 0
In this example, multiple MAC router mode is enabled (the switch’s default setting).
For detailed information on multiple and single MAC router modes, refer to the “Configuring VLANs”
chapter in the
OmniSwitch 7700/7800/8800 Network Configuration Guide
.
Note.
When VLAN router ports are assigned in multiple MAC router mode, the syntax,
mac alloc
, is
written to the switch’s
boot.cfg
file whenever a
write memory
or
configuration snapshot
command is
issued. For example, text similar to the following may appear in the
boot.cfg
file:
mac alloc 8 2 1 00:d0:95:6a:68:11
This
mac alloc
syntax is not a user command. Therefore, do not attempt to enter this syntax at the CLI
prompt. It is system-generated syntax used to ensure that each new router port being assigned receives a
unique MAC address. For more information about editing the
boot.cfg
file, see the
OmniSwitch 7700/
7800/8800 Switch Management Guide
.
