Hi Blue,
You can access all or specific stack members by using the "remote command {all | stack-member-number}" privileged EXEC command. The stack member number range is 1 to 9.
You can access specific stack members by using the "session stack-member-number" privileged EXEC command. The stack member number range is 1 to 9. The stack member number is appended to the system prompt. For example, Switch-2# is the prompt in privileged EXEC mode for stack member 2, and the system prompt for the stack master is Switch. Enter exit to return to the CLI session on the stack master. Only the show and debug commands are available in a CLI session to a specific stack member.
