Interface

Interface
Note If the management 10/100 Ethernet port (mgmt0) interface of the Cisco MDS 9700 Series switches has a
preconfigured /0 IPv6 address that cannot be removed, use the write erase boot command to clear the
complete configuration of the device and reload it. Perform this process before commissioning the device
into production as this process is disruptive to user traffic if it is applied to the active supervisor of a
system. Ensure an active console connection to the supervisor as this process will remove the IPv4 address
of the mgmt0 interface.
The management interface allows multiple simultaneous Telnet or SNMP sessions. You can remotely configure
the device through the management interface (mgmt0), but first you must configure some IP parameters so
that the switch is reachable. You can manually configure the management interface from the CLI. You can
configure the mgmt 0 interface with either IPv4 address parameters or an IPv6 address.
On devices with dual supervisor modules, a single IP address is used to manage the switch. The active
supervisor module's mgmt0 interface uses this IP address. The mgmt0 interface on the standby supervisor
module remains in an inactive state and cannot be accessed until a switchover happens. After a switchover,
the mgmt0 interface on the standby supervisor module becomes active and assumes the same IP address as
the previously active supervisor module.
The management port (mgmt0) is autosensing and operates in full duplex mode at a speed of 10/100/1000
Mbps. Autosensing supports both the speed and the duplex mode.

Default Gateway

The supervisor module sends IP packets with unresolved destination IPv4 addresses to the default gateway.
