Viewing and Clearing Stacking and NSF Information
Beginning in Privileged EXEC mode, use the following commands to view
stacking information and to clear NSF statistics.
Connecting to the Management Console from a Stack Member
From the CLI Unavailable prompt, use the following command to connect
the console session to the local unit.
NOTE: The OSPF feature uses NSF to enable the hardware to continue forwarding
IPv4 packets using OSPF routes while a backup unit takes over stack master
responsibility. Additional NSF commands are available in OSPF and OSPFv3
command modes. For more information, see "NSF OSPF Configuration " on
page 1207 and "NSF OSPFv3 Configuration " on page 1224
