4.6 Problems and Solutions
The following sections describe problems you may encounter in using the NMS.
PC Cannot Locate Web Server
The PC being used to access NMS keeps a record of IP (Internet Protocol) and
MAC (Medium Access Control) addresses in its local ARP (Address Resolution
Protocol) cache. If the same computer is used to access NMS through the
local management port and then again to access NMS through a network
connection, the local ARP cache can prevent the computer from "finding" the
embedded web server. Though the ARP cache will eventually clear itself as
entries time out, it can also be cleared manually:
1. Click on the Windows Start button.
2. Select Run.
3. Type cmd and click on OK to open a command prompt.
4. At the prompt, type
arp -a
and press the Enter key.
This will return a list of all the IP Addresses in the computer's ARP cache.
5. If the IP address you wish to clear is listed, type:
arp -d [the IP Address]
at the prompt and press the Enter key.
Web Pages Are Loading Slowly
If NMS pages are accessible but refreshing slowly, close all browser windows
and
re-launch the application. If the problem continues, you may be encountering
one
of the following conditions:
1. Too Many Users – NMS can supports up more users simultaneously. But the
system may experience a slowdown if there are so many users at a time.
Likewise, new users cannot log in at the same time. Please attempt later if
some user logout.
2. Inband Connection Speed not set appropriately – The speed setting may
need to be increased if you are accessing the system via an inband
connection from a remote customer site (e.g., through a provisioned SHDSL
connection). As an example, a 128 kbps DSL connection is generally
sufficient for NMS access although it is possible for heavy traffic to cause
