Administrator Guide

● prefix must contain the gateway.
● gateway must be a unique address on the local cluster.
Note the following:
● A cleared address is contained by all prefixes and matches no addresses.
● A cleared prefix contains all addresses.
● A property that is not present in a particular subnet context is considered cleared.
If a change is made to the subnet, the change is validated and applied to all ports using this subnet.
When re-configuring a port-group, there are multiple values that must be consistent with each other. It may be necessary to
clear or erase some attribute values before others can be changed.

To clear a subnet, use configuration subnet clear command.
/connectivity/back-end/
The back-end role context contains the configuration information required to connect to back-end storage arrays.
The back-end role does not have any associated properties. Note that only IP port-groups have subnet contexts.
port-groups/ip-port-group-*/subnet/
The back-end role context has subnets that allow you to configure routing to access targets with addresses that are not
contained by prefix.
The following is a description of the subnet attributes:
● gateway - The address of the gateway associated with this subnet.
● mtu - The maximum transfer unit for this subnet.
● prefix - The prefix and mask for this subnet.
● remote-subnets - Prefixes of the remote networks reachable from this subnet.
Refer to subnets context for information on modifying or clearing these attributes.
/connectivity/front-end/
The front-end role context contains the configuration information required to connect to front-end hosts.
The front-end role has subnets that allow you to configure routing to access hosts with addresses that are not contained by
prefix. Note that only IP port-groups have subnet contexts.
The following is a description of the /connectivity/front-end/ context subnet attributes:
● gateway - The address of the gateway associated with this subnet.
● mtu - The maximum transfer unit for this subnet.
● prefix - The prefix and mask for this subnet.
● remote-subnets - Prefixes of the remote networks reachable from this subnet.
The remote-subnet attribute is a list that can be modified using the configuration subnet remote-subnets add
and configuration subnet remote-subnets remove commands.
Refer to subnets context for information on modifying or clearing other attributes.
