Managing a Stack
The stack is managed primarily through the Master switch. The Master switch then
pushes configuration changes and run-time information to the Member switches.
Use Telnet or the Browser-Based Interface (BBI) to access the Master, as follows:
•
Use the management IP address assigned to the Master by the management
system.
• On any switch in the stack, connect to any port that is not part of an active trunk,
and use the IP address of any IP interface to access the stack.
Stacking Port Numbers
Once a stack is configured, port numbers are displayed throughout the BBI using
the
csnum
to identify the switch, followed by the switch port number. For example:
Stacking VLANs
VLAN 4090 is the default VLAN reserved for internal traffic on stacking ports.
Note: Do not use VLAN 4090 for any purpose other than internal stacking traffic.
Rebooting Stacked Switches using the ISCLI
The administrator can reboot individual switches in the stack, or the entire stack
using the following commands:
Rebooting Stacked Switches using the BBI
