Chapter3 Managing ITP Networks Using SGM
Working with Links
Configuration Data Tab: Configured Local IP Address Information (SCTP Links Only)
To view configured local IP address information for the selected SCTP link, select
the Configuration Data tab.
The Configured Local IP Address Information sub-section displays the following
information for the selected link:
•IP Address—Configured local IP address associated with the link.
•Interface Name—Primary IP address and interface name of the link. The
primary IP address is the first CS7 local IP address configured in the ITP. For
example, if the following IP addresses are configured in the ITP:
cs7 local-peer 4180
local-ip 128.3.0.77
local-ip 128.3.0.254
Then SGM uses 128.3.0.77 as the primary IP address. If at any time that IP
address is deleted from the ITP configuration, or if a new IP address is added
to the beginning of the list, SGM detects the change and automatically
updates this field to reflect the new primary IP address.
If the link has no interface name, this field is blank.
Status Summary Tab: Status Information
To view status information for the selected link, select the Status Summary tab.
The Status Information sub-section displays the following information for the
selected link:
•Last Status Change—Date and time that the status of the link last changed.
•Status—Current status of the link. Possible values are:
–
Active (green ball)—The link is currently fully functional.
–
Blocked (red ball)—Traffic on this link is disabled by protocol.
–
Failed (red ball)—An error is preventing traffic from flowing on this
link, or the associated linkset has been set to Shutdown status.
A link can be Failed from an MTP3 perspective, but control messages
might still be sent or received on the link, resulting in changing
packet/second and bit/second rates. The rates might also be different at
each end of the link, depending on the reason for the failure and the
timing related to each endpoint.
