Assigning IP Addresses to Switches in a Stacked Configuration It is important that all switches in a stacked configuration have the same assigned IP address. This way, if a failover should occur (i.e., another switch in the stack assumes the primary management role), users can still log in to the stack via remote login sessions such as Telnet, FTP, and WebView. The IP assigned to the stack's primary switch is dynamically assigned to all other switches in the stack whenever either of the following actions occurs: • The entire stack is rebooted • The copy flash-synchro command is entered at the CLI prompt on the stack's primary switch You are not required to manually assign the IP address to each switch in the stack. Avoiding Duplicate IP Addresses in the Network. If any stacking cable (other than the optional redundant stacking cable) is disconnected while the stack is in operation, a duplicate IP addresses will exist on the network. Therefore, if a switch is to be pulled from a stack, it is recommended that the switch is given a unique IP address via the (ip interface command) before being disconnected. Unlocking Session Types Security is a key feature on OmniSwitch 6600 Family switches. As a result, when you access the switch for the first time, you must use a direct console port connection. All other session types (Telnet, FTP, WebView, SNMP, etc.) are "locked out" until they are manually unlocked by the user. The CLI command used to unlock session types is aaa authentication. Note. When you unlock session types, you are granting switch access to non-local sessions (e.g., Telnet). As a result, users who know the correct user login and password will have remote access to the switch. For more information on switch security, refer to the "Managing Switch User Accounts" chapter of your OmniSwitch 6600 Family Switch Management Guide. Unlocking All Session Types To unlock all session types, enter the following command syntax at the CLI prompt: -> aaa authentication default local 34 Your First Login Session March 2005
