Cabletron Systems TSX-1620 2-10 Monitoring Device Performance

Using the TSX-1620 Hub View

2-10 Monitoring Device Performance

• A status of OFF indicates that the port has been physically disabled, or is

broken.

•NLK (no link) indicates that the interface’s operational status is determined as

“UP”, and it has been administratively enabled, but no physical link state to

the port has been detected.

• A status of Test indicates that the interface is in some operational or

administrative test status, and is unable to pass packets.

• The --- (unknown) status indicates that the state of the port’s operational, link,

and administrative states were not returned from the device.

Type

Displays the MIB-II ifType. As deﬁned by the MIB “the type of interface,

distinguished according to the physical/link protocol(s) immediately below the

network layer in the protocol stack.”

Speed

Displays the operating speed of the interface; as deﬁned by the MIB-II ifSpeed,

“An estimate of the interface’s current bandwidth in bits per second. For

interfaces which do not vary in bandwidth or for those where no accurate

estimation can be made, this object should contain the nominal bandwidth.”

Interface Number

Displays each port’s interface number, including the network management port.

Statistics

From the Interface or Bridge menu, you can display any one of the statistics

detailed below:

•Load will display the percentage of total, inbound, or outbound network load

processed by each port during the last polling interval.

- Total will display the percentage of total, inbound, and outbound network

load processed by each port during the last polling interval. This

percentage reﬂects the network load generated per polling interval by

devices connected to the port (determined by adding the change in the

port’s MIB-II ifInOctets and ifOutOctets values during the last polling

interval and multiplying by 800) compared to the port’s ifSpeed value.

- In shows the percentage of packets received during the last polling

interval from devices connected to the port. This percentage reﬂects the

packets received (determined by the change in the port’s MIB-II ifInOctets

value during the last polling interval, multiplied by 800) compared to the

port’s ifSpeed value.
