Management Interface Configuration

</h1>
<a name="wp1072877"> </a><p class="pBody">
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 <a href="ipv601.html">&quot;Configuring IPv6 
for Gigabit Ethernet Interfaces.&quot;</a>

</p>
<a name="wp1072881"> </a><p class="pBody">
On director class switches, a single IP address is used to manage the switch. The active supervisor 
module&#39;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.

</p>
<a name="wp1072882"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> The port on the Ethernet switch to which the MDS management interface is connected should be 
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 <b class="cBold">switchport host </b>command in 
Cisco IOS is or the <b style="font-weight: bold" class="cBold">set port host </b><b style="font-weight: normal" class="cBold">command</b><b class="cBold"> </b>in the Catalyst OS. Refer to the configuration guide for your 
Ethernet switch.

</p>
<a name="wp1072883"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> Before you begin to configure the management interface manually, obtain the switch’s IP address and IP 
subnet mask. Also make sure the console cable is connected to the console port.
