Gigabit Ethernet Interfaces for IPv4 Configuration

</h1>
<a name="wp1073184"> </a><p class="pBody">
Both FCIP and iSCSI rely on TCP/IP for network connectivity. On each IPS module or MPS-14/2 
module, connectivity is provided in the form of Gigabit Ethernet interfaces that are appropriately 
configured. 

</p>
<a name="wp1073188"> </a><p class="pBody">
A new port mode, called IPS, is defined for Gigabit Ethernet ports on each IPS module or MPS-14/2 
module. IP storage ports are implicitly set to IPS mode, so it can be used to perform only iSCSI and FCIP 
storage functions. IP storage ports do not bridge Ethernet frames or route other IP packets.

</p>
<a name="wp1073191"> </a><p class="pBody">
Each IPS port represents a single virtual Fibre Channel host in the Fibre Channel SAN. All iSCSI hosts 
connected to this IPS port are merged and multiplexed through the single Fibre Channel host.

</p>
<a name="wp1073195"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> For information about configuring FCIP, see <a href="cfcip01.html">&quot;Configuring FCIP.&quot;</a> For information about configuring 
iSCSI, see <a href="ciscsi001.html">&quot;Configuring iSCSI.&quot;</a>

</p>
<a name="wp1073199"> </a><p class="pBody">
In large scale iSCSI deployments where the Fibre Channel storage subsystems require explicit LUN 
access control for every host device, use of proxy-initiator mode simplifies the configuration.

</p>
<a name="wp1073200"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> The Gigabit Ethernet interfaces on the MPS-14/2 module do not support EtherChannel.

</p>
<a name="wp1073201"> </a><p class="pBodyAutonumNoRule">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> To configure IPv6 on a Gigabit Ethernet interface, see the <span style="font-style: italic">Security Configuration Guide, Cisco DCNM 
for SAN</span>.

</p>
<a name="wp1073202"> </a><p class="pBodyAutonumRel">
<strong>Tip	&nbsp;&nbsp;&nbsp;</strong> Gigabit Ethernet ports on any IPS module or MPS-14/2 module should not be configured in the same 
Ethernet broadcast domain as the management Ethernet port&#8212;they should be configured in a different 
broadcast domain, either by using separate standalone hubs or switches or by using separate VLANs.
