Modifying a subnet group
You can modify a subnet group's description, or modify the list of subnet IDs associated with the subnet group. You cannot delete a subnet ID from a subnet group if a cache is currently using that subnet.
The following procedures show you how to modify a subnet group.
Modifying subnet groups (Console)
To modify a subnet group
-
Sign in to the Amazon Web Services Management Console and open the ElastiCache console at https://console.amazonaws.cn/elasticache/
. -

-
In the list of subnet groups, select the radio button of the one you want to modify and choose Modify.

Modifying subnet groups (Amazon CLI)
At a command prompt, use the command modify-cache-subnet-group
to
modify a subnet group.
For Linux, OS X, or Unix:
aws elasticache modify-cache-subnet-group \ --cache-subnet-group-name
mysubnetgroup
\ --cache-subnet-group-description"New description"
\ --subnet-ids "subnet-42df9c3a
" "subnet-48fc21a9
"
For Windows:
aws elasticache modify-cache-subnet-group ^ --cache-subnet-group-name
mysubnetgroup
^ --cache-subnet-group-description"New description"
^ --subnet-ids "subnet-42df9c3a
" "subnet-48fc21a9
"
This command should produce output similar to the following:
{ "CacheSubnetGroup": { "VpcId": "vpc-73cd3c17", "CacheSubnetGroupDescription": "New description", "Subnets": [ { "SubnetIdentifier": "subnet-42dcf93a", "SubnetAvailabilityZone": { "Name": "us-west-2a" } }, { "SubnetIdentifier": "subnet-48fc12a9", "SubnetAvailabilityZone": { "Name": "us-west-2a" } } ], "CacheSubnetGroupName": "mysubnetgroup" } }
