Setting up IP addresses for a logical switch

Setting up IP addresses for a logical switch
Each physical chassis has one common IP address that is shared by all of the logical switches in
the chassis. You can also set up individual IPv4 addresses for each logical switch.
IPv4 addresses assigned to individual Virtual Fabrics are assigned to IP over Fibre Channel (IPFC)
network interfaces. In Virtual Fabrics environments, a single chassis can be assigned to multiple
fabrics, each of which is logically distinct and separate from one another. Each IPFC point of
connection to a given chassis needs a separate IPv4 address and prefix to be accessible to a
management host.
For a management host to access logical switches, the host bus adapter (HBA) must be able to
connect with the common, shared IP address and the individual IPv4 addresses configured for
each logical switch.
NOTE
IPv6 is not supported when setting the IPFC interface for Virtual Fabrics.
Use the following procedure to set up IP addresses for a logical switch:
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the ipAddrSet -ls command. For the
--add parameter, specify the network information in
dotted-decimal notation for the Ethernet IPv4 address with a Classless Inter-Domain Routing
(CIDR) prefix.
The following example sets an IP address for a logical switch in a Virtual Fabric with an FID of
123 in non-interactive mode with the CIDR prefix:
switch:admin> ipaddrset -ls 123 --add 11.1.2.4/24
Removing an IP address for a logical switch
Use the following procedure to delete an IP address for a logical switch:
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the ipAddrSet -ls FID - -delete command.
switch:admin> ipaddrset -ls 123 –delete
Configuring a logical switch to use XISLs
When you create a logical switch, it is configured to use XISLs by default. Use the following
procedure to allow or disallow the logical switch to use XISLs in the base fabric.
XISL use is not supported in some cases. See “Limitations and restrictions of Virtual Fabrics” on
page 322 for restrictions on XISL use.
Use the following procedure to configure a logical switch to use XISLs:
1. Connect to the physical chassis and log in using an account with the chassis-role permission.
2. Use the setContext command to set the context to the logical switch you want to manage, if you
are not already in that context.
