MONITORING

4.1 DISPLAYING PORT STATUS

Using LCM, you can obtain the status of ports by typing status for the

appropriate port. A sample display is shown below.

4.1.1 Status Command

ATX >status 2

Port 2 (1st port on module 3) status

Type: Ethernet/802.3 CSMA/CD

Bridging: Transparent/Translating

Routing: IP Routing RIP

Enabled/Disabled: Bridging/Routing functions enabled

Spanning Tree: Forwarding

Pkts Transmitted: 503

Pkts Received: 89711

Small Buffers: 23

Rx_Q Overflows: 10

Carrier Losses: 9

Total Collisions: 184

Excess Collisions: 5

Rx FCS/Align Errs: 0

Internal Rx Errors: 0

Internal Tx Errors: 0

The status of the port includes the following information:

• Bridging - which functions have been enabled for bridging (see the

bridge command).

• Routing - which functions have been enabled for routing (see

iproute

and

ipxroute commands in your NMS manual).

• Enabled/Disabled - enabled if it is operational or, disabled if you used

the disable command to disable it. If the port is enabled but not

operational, its status will be broken. (A port could be broken if it is so

badly misconﬁgured as to be unusable. You might also see a status of

broken if an FDDI or Token Ring port can’t connect to a logical ring,

or if an Ethernet port continually fails as it tries to transmit.)
