Field Description
Total Clusters A cluster is the physical interface upon which Fast
Rer
oute link protection has been enabled.
Total Groups A group is a database record that associates the
l
ink-protected physical interface with a backup
tunnel. A cluster (physical interface) therefore can
have one or more groups.
For example, the cluster Ethernet4/0/1 is protected by
bac
kup Tunnel1 and backup Tunnel2, and so has two
groups.
Total Items An item is a database record that associates a rewrite
w
ith a group. A group therefore can have one or more
items.
Link 10:PO5/0 (Down, 1 group) This describes a cluster (physical interface):
• “10” is the interface’s unique IOS-assigned ID
number.
• “:” is followed by the interface’s short name.
• Parentheses contain the operating state of the
interface (Up or Down) and the number of groups
associated with it.
Group 51:PO5/0->Tu4000 (Up, 779 members) This describes a group:
• “51” is the ID number of the backup interface.
• “:” is followed by the group’s physical interface
short name.
• “->” is followed by the backup tunnel interface
short name.
• Parentheses contain the operating state of the
tunnel interface (Up or Down) and the number of
items—also called “members”— associated with
it.
