Configuring IPv4 for Gigabit Ethernet Interfaces
Cisco MDS 9000 Family supports IP version 4 (IPv4) on Gigabit Ethernet interfaces. This chapter
describes how to configure IPv4 addresses and other IPv4 features.
This chapter includes the following topics:
• About IPv4, page 53-1
• Basic Gigabit Ethernet Configuration for IPv4, page 53-2
• VLANs, page 53-4
• IPv4-ACLs, page 53-6
• Default Settings, page 53-6
About 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 48, “Configuring FCIP.” 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 “Configuring IPv6 Addressing and Enabling
IPv6 Routing” section on page 54-11.
