Review Table 5-5 for symptoms and possible solutions to help in solving any
network problems you may encounter in the Hotwire DSL system.
Table 5-5. Network Problems (1 of 3)
Problem
Action
Cannot
communicate
with Ethernet or
other interface
after adding,
changing, or
deleting IP
addresses on
DSL or MCC
card.
When you add, change, or delete addresses on a DSL card, you must
restart that interface (see Configuration → Interfaces (A-C) in
Chapter 3, RADSL Card Configuration).
Cannot
establish an
SNMP session/
connection.
1. Try to Ping the MCC card and/or DSL card from the management
system.
2. If you cannot, check to see that you have entered an IP address
and subnet mask (see Who Am I screen in the Hotwire
Management Communications Controller (MCC) Card User’s
Guide.
3.
If there is an IP address, then check the routing tables in the MCC
card and RADSL card.
4. Check to see if the community string is correct.
5. If IP Address Security is enabled, check to see that Network
Management’s IP address has been entered correctly in the MCC
card’s and RADSL card’s permission list and that it has proper
access.
6. Check to see if you have properly configured the SNMP parameters
(see Monitoring → Network Protocol (B-D) in Chapter 4, Monitoring
the Hotwire DSL System, and Configuration → SNMP (A-F) in
Chapter 3, RADSL Card Configuration).
