Configuring Gigabit Ethernet Interfaces for IPv4
Configuring Gigabit Ethernet Interfaces for IPv4
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. This section covers the steps required to configure IP for subsequent use by FCIP and iSCSI.
Note For information about configuring FCIP, see Chapter 5, “Fabric Manager Client”. For information about
configuring iSCSI, see Chapter 50, “Configuring iSCSI”.
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 only be used to perform iSCSI and FCIP
storage functions. IP storage ports do not bridge Ethernet frames or route other IP packets.
Each IPS port represents a single virtual Fibre Channel host in the Fibre Channel SAN. All the iSCSI
hosts connected to this IPS port are merged and multiplexed through the single Fibre Channel host.
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.
Note The Gigabit Ethernet interfaces on the MPS-14/2 module do not support EtherChannel.
Note To configure IPv6 on a Gigabit Ethernet interface, see the “Gigabit Ethernet IPv6-ACL Guidelines”
section on page 54-14.
Tip 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—they should be configured in a different
broadcast domain, either by using separate standalone hubs or switches or by using separate VLANs.
Basic Gigabit Ethernet Configuration
Figure 52-3 shows an example of a basic Gigabit Ethernet IP version 4 (IPv4) configuration.

Note The port on the Ethernet switch to which the MDS Gigabit Ethernet 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
management port coming up due to delay from Ethernet spanning tree processing that the Ethernet
