Configuring Ports
CM provides different configuration options for each type of port. The options available to each port
will appear in the Port Properties window.
Configuring a Port Name
To configure the administrative name of a port:
1. Expand the Chassis icon in the Tree frame.
2. Click the Ports branch. The Ports table appears in the View frame. A radio button appears to the
left of each table entry.
3. Click the radio button of the port to which you want to assign a name.
In Multicast Packets Cumulative number of incoming packets destined for the ports of a
multicast group.
In Broadcast Packets Cumulative number of incoming packets destined for all ports on the
fabric.
In Discards Cumulative number of inbound packets that the port discarded for a
reason other than a packet error (for example, lack of buffer space).
In Errors Number of inbound packets with errors that the port discarded.
In Unknown
Protocols
For packet-oriented interfaces, the number of packets received through
the interface that were discarded because of an unknown or unsupported
protocol. For character-oriented or fixed-length interfaces that support
protocol multiplexing, the number of transmission units received through
the interface that were discarded because of an unknown or unsupported
protocol. For any interface that does not support protocol multiplexing,
this counter is always 0.
Out Octets Total number of octets transmitted out of the interface, including framing
characters.
Out Unicast Packets Total number of packets that higher-level protocols requested be
transmitted, and which were not addressed to a multicast or broadcast
address at this sub-layer, including those that were discarded or not sent.
Out Multicast Packets Total number of packets that higher-level protocols requested be
transmitted, and which were addressed to a multicast address at this
sub-layer, including those that were discarded or not sent. For a MAC
layer protocol, this includes both Group and Functional addresses.
Out Broadcast
Packets
Total number of packets that higher-level protocols requested to be
transmitted, and which were addressed to a broadcast address at this
sub-layer, including those that were discarded or not sent.
Out Discards Number of outbound packets that were chosen to be discarded even
though no errors had been detected to prevent their being transmitted.
One possible reason for discarding such a packet could be to free-up
buffer space.
Out Errors For packet-oriented interfaces, the number of outbound packets that
could not be transmitted because of errors. For character-oriented or
fixed-length interfaces, the number of outbound transmission units that
could not be transmitted because of errors.
