Traffic Management Services

In-band options are compliant with and use the RFC 2625 standards. An NMS host running the IP
protocol over an Fibre Channel interface can access the switch using the IPFC functionality. If the NMS
does not have a Fibre Channel HBA, in-band management can still be performed using one of the
switches as an access point to the fabric (see

Management Interface Configuration

The management interface on the switch allows multiple simultaneous Telnet or SNMP sessions. You
can remotely configure the switch through the management interface, but first you must configure IP
version 4 (IPv4) parameters (IP address, subnet mask) or an IP version 6 (IPv6) address and prefix length
so that the switch is reachable. For information on configuring IPv6 addresses, see
"Configuring IPv6 for Gigabit Ethernet Interfaces."
On director class switches, a single IP address is used to manage the switch. The active supervisor
module's management (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 port on the Ethernet switch to which the MDS management interface is connected should be
Note
configured as a host port (also known as access port) instead of a switch port. Spanning tree
configuration for that port (on the Ethernet switch) should disabled. This helps avoid the delay in the
MDS management port coming up due to delay from Ethernet spanning tree processing that the Ethernet
switch would run if enabled. For Cisco Ethernet switches, use either the switchport host command in
Cisco IOS is or the set port host command in the Catalyst OS. Refer to the configuration guide for your
Ethernet switch.
