Map Problems; Script Problems - ZyXEL Communications ENTERPRISE NETWORK CENTER Manual

Check if the auto-discovery program is still active (you can see a Stop button in the Auto-
4a
Discovery screen if it is; otherwise, a Discover button displays instead). Wait for a while and
check the OTV again if the program is running.
Make sure your auto-discovery filter rule(s) do not exclude the device.
4b
If the device supports SNMP, make sure you configure the same SNMP version and community
4c
on the ENC. The device's SNMP (port 161) should also be enabled.
You may have a firewall between the ENC and the device that blocks auto-discovery packets.
4d
You may need to stop it or configure a firewall rule to allow traffic between them.
If the device does not support SNMP, you can use ping to find it by selecting Enable Ping in
4e
the Auto-Discovery screen. If the device does not respond to ping, disable any anti-probe
related function on the device.
Click the Refresh icon to update the device list in the OTV.

10.4 Map Problems

I cannot see the Map image that I have uploaded.
Make sure your web browser and the version of it support the image display. See
page 17 for the browser requirements.
I received "Discover is only allowed on default map" when I perform Auto-Discovery.
Auto-Discovery only searches for and adds devices to the default Map. You have to switch the Map
to the default one by clicking the Map icon on the left hand of the screen and then changing the
Map in the Map > Open screen.

10.5 Script Problems

I see "Connection Error" when I execute a script.
Make sure the telnet service is enabled on the device(s) to which you want to apply the script.
1
Make sure there are not any firewall devices between the ENC and the device(s) or configure a
2
firewall rule on them, which allows telnet access from the ENC to the device. Try to turn the firewall
off first to see if it helps.
