12.11.3 MSC RMON Statistics
To view RMON statistics on a switch port, click on the ID for the MSC card in the Port Statistics
screen and click the RMON tab.
BCastPkts This is the number of good broadcast frames received/transmitted of 64 to 1518 octets in
length (for non VLAN) or 1522 octets (for VLAN), not including multicast frames. Frames
with range or length errors are also not taken into account.
Discards This is the number of frames this port has discarded.
Errors This is the number of errors recorded on this port.
Pause This is the number of valid IEEE 802.3x Pause frames received/transmitted on this port.
Pkt64 This is the number of frames received/transmitted (including bad frames) that were 64
octets or less in length (this includes FCS octets but excludes framing bits).
Pkt65~127 This is the number of frames received/transmitted (including bad frames) that were 65 to
127 octets in length (this includes FCS octets but excludes framing bits).
Pkt128~255 This is the number of frames received and transmitted (including bad frames) that were 128
to 255 octets in length (this includes FCS octets but excludes framing bits).
Pkt256~511 This is the number of frames received/transmitted (including bad frames) that were 256 to
511 octets in length (this includes FCS octets but excludes framing bits).
Pkt512~1023 This is the number of frames received/transmitted (including bad frames) that were 512 to
1023 octets in length (this includes FCS octets but excludes framing bits).
Pkt1024~1518 This is the number of frames received/transmitted (including bad frames) that were 1024 to
1518 octets in length (this includes FCS octets but excludes framing bits).
Oversize This is the number of frames received/transmitted that were bigger than 1518 (non VLAN)
or 1522 (VLAN) octets and contained a valid FCS.
Undersize This is the number of frames received/transmitted that were less than 64 octets long and
contained a valid FCS.
FCSError This is the number of frames received/transmitted with an integral length of 64 to 1518
octets and containing a Frame Check Sequence error.
AlignError This is the number of frames received/transmitted that were 64 to 1518 (non VLAN) or 1522
(VLAN) octets long but contained an invalid FCS and a non-integral number of octets.
Jabber This is the number of frames received/transmitted that were longer than 1518 octets (non
VLAN) or 1522 octets (VLAN) and contained an invalid FCS, including alignment errors.
Fragment This is the number of frames received/transmitted that were less than 64 octets long, and
contained an invalid FCS, including non-integral and integral lengths.
Dropped This is the number of received/transmitted frames that were received by the MSC, but later
dropped because of a lack of system resources.
Underrun This is the number of outgoing frames that were less than 64 octets long.
Collision This is the number of frames for which transmission failed due to excessive collisions.
Excessive collision is defined as the number of maximum collisions before the
retransmission count is reset.
