LACP Mode Selects the Link Aggregation Control Protocol administration state:
• Enable: Specifies that the port is allowed to participate in a port channel
(LAG), which is the default mode.
• Disable: Specifies that the port cannot participate in a port channel
(LAG).
Physical Mode Indicates the port speed and duplex mode. In auto-negotiation mode, the
duplex mode and speed are set from the auto-negotiation process.
Physical Status Indicates the port speed and duplex mode status.
Link Status Indicates whether the link is up or down.
Link Trap This object determines whether or not to send a trap when link status
changes. The factory default is Enable.
• Enable: Specifies that the system sends a trap when the link status
changes.
• Disable: Specifies that the system does not send a trap when the link
status changes.
Packets RX and TX 64
Octets
The total number of packets (including bad packets) received or transmitted
that were 64 octets in length (excluding framing bits but including FCS octets).
Packets RX and TX 65-127
Octets
The total number of packets (including bad packets) received or transmitted
that were between 65 and 127 octets in length inclusive (excluding framing
bits but including FCS octets).
Packets RX and TX
128-255 Octets
The total number of packets (including bad packets) received or transmitted
that were between 128 and 255 octets in length inclusive (excluding framing
bits but including FCS octets).
Packets RX and TX
256-511 Octets
The total number of packets (including bad packets) received or transmitted
that were between 256 and 511 octets in length inclusive (excluding framing
bits but including FCS octets).
Packets RX and TX
512-1023 Octets
The total number of packets (including bad packets) received or transmitted
that were between 512 and 1023 octets in length inclusive (excluding framing
bits but including FCS octets).
Packets RX and TX
1024-1518 Octets
The total number of packets (including bad packets) received or transmitted
that were between 1024 and 1518 octets in length inclusive (excluding framing
bits but including FCS octets).
Packets RX and TX > 1522
Octets
The total number of packets (including bad packets) received or transmitted
that are in excess of 1522 octets in length inclusive (excluding framing bits but
including FCS octets).
Octets Received The total number of octets of data (including those in bad packets) received on
the network (excluding framing bits but including FCS octets). This object can
be used as a reasonable estimate of ethernet utilization. If greater precision is
desired, the etherStatsPkts and etherStatsOctets objects should be sampled
before and after a common interval.
Packets Received 64
Octets
The total number of packets (including bad packets) received that were 64
octets in length (excluding framing bits but including FCS octets).
