Cannot connect using

Telnet, Web browser,

or SNMP software

• Be sure you have configured the agent with a valid

address, subnet mask and default gateway.

• If you are trying to connect to the agent via a tagged VLAN

group, your management station must include the

appropriate tag in its transmitted frames.

• Check that you have a valid network connection to the

switch and that the port you are using has not been

disabled.

• Check network cabling between the management station

and the switch.

• If you cannot connect using Telnet, there may already be

four active sessions. Try connecting again at a later time.

configuration

program via a serial

port connection

• Be sure you have set the terminal emulator program to

VT100 compatible, 8 data bits, 1 stop bit, no parity, and

9600 bps.

• Check that the null-modem serial cable conforms to the

pin-out connections provided in the Installation Guide.
