3Com 6416SW manual Client, Steps Take, Ping ARP, Okay

ONcore

Hub

Cannot PING

an

ARP

Client

Steps

to

Take:

Check

if

the

ONcore hub can ping the ARP server.

If

not,

then

see

“ONcore

Cannot

PING

the

ARP

Servers and

Vice-versa”

on

page 7-25.

If

it

can

ping

the

server:

1. The

port

of

the

ARP

client

is

not

OKAY.

Check

that

the

port of that ARP client is enabled. If it

is

enabled,

and

not OKAY

then

the

problem comes

from

the

ARP

client or

from

the cable attached to

it.

2. The ARP client is not registered in the ARP server.

Check	that	the	ARP	client		has	TCP/IP running, and	that	the	address	configured for
its	ARP server		is	correct.
3. If	the	ONcore	hub		and	the	ARP client are not	in	the	same IP	subnet, there may
a Gateway		definition			problem.

Check the Default Gateway addresses in both machines. In general, they correspond to one common gateway.

4. The	SVC	between	the ONcore	hub	and the ARP client cannot be established.
Check the Clear-Log Table in				the	Transcend ONcore ATM Campus Manager ATM
(ATMC)	to	see the	cause of	the	failure.
