Advanced Suggestions
Try to access the MES-2110 using another service, such as Telnet or over the
console port. If you can access the MES-2110, check the remote management
settings to find out why the MES-2110 does not respond to HTTP.
Some possible reasons for being unable to connect over the in-band management
ports are that you:
1
Deleted the management VLAN (default is VLAN 1).
2
Deleted all port-based VLANs with the CPU port as a member. The “CPU port” is
the management port of the MES-2110.
3
Filtered all traffic to the CPU port.
4
Disabled all ports.
5
Misconfigured the text configuration file.
6
Prevented all services from accessing the MES-2110.
