Chapter 8 Interface and Subinterface Management
Serial Subinterface Management—Configuration Window
•
Connector Present—Displays if a cable is attached to the parent interface (the OSM Channelized
SONET Interface). These are the values:
–
yes
–
no
–
unknown—This value is used when the Administrative Status is not set to “up”. In this case, it
cannot be determined if a connection is present or not.
•
Last Change—The value (in seconds) of sysUpTime at the time the interface entered its current
operational state. If the current state was entered before the last reinitialization of the local network
management subsystem, then this object contains a zero value. This attribute is read-only.
Configuration Tab
The following areas are available on the Configuration tab of the Serial Subinterface Management -
Configuration window:
•
General
•
Layer 2
•
Layer 3
General
The General area contains the following information:
•
Link Up / Down Trap—Enables or disables linkUp and linkDown trap generation for the interface.
•
Bandwidth—Overwrites default bandwidth in kilobits per second.
Note
The Bandwidth attribute is an informational parameter used only to communicate the current
bandwidth to the higher-level protocols (such as IGRP, EIGRP, and OSPF); you cannot adjust
the actual bandwidth of an interface with this command.
•
Delay—Specifies the delay in tens of microseconds for an interface or network segment.
Note
The Delay attribute is an informational parameter used only to communicate the current
bandwidth to the higher-level protocols (such as IGRP and EIGRP); you cannot adjust the actual
delay of an interface with this command.
•
Max. Input Queue Length—Displays the input queue length in packets.
•
Max. Output Queue Length—Displays the output queue length in packets.
Layer 2
The Layer 2 area contains the following information:
•
MTU—The size of the largest datagram (frame) which can be sent or received on the interface,
specified in octets.
•
Advanced Features—Launches the Serial Sub–Interface Advanced Configuration window.
