CMMVC8024E
The set service assistant IP address task failed because a required gateway, IPv4 subnet mask, or IPv6 prefix was not specified.

#### Explanation

When you define the service assistant IP address on a candidate canister in either IP version format, you must specify the gateway. For IPv4, you must also specify the subnet mask. For IPv6, you must also specify the prefix.
Note: You can change the service IP of a canister in any state, whether `candidate`, `active` or `service`; however, the initial definition on a candidate canister has the additional requirements previously stated.

#### User response

Specify all of the required information when you set the service assistant IP address on a candidate canister. See Resolving a problem topics in the Troubleshooting section of the Information Center.
