Managing from an NMS 59
n
To improve security and prevent attack to the unused Sockets, TCP 80 port (which
is for HTTP service) is enabled/disabled after the corresponding configuration.
■ Enabling the Web server (by using the undo ip http shutdown command)
opens TCP 80 port.
■ Disabling the Web server (by using the ip http shutdown command) closes
TCP 80 port.
Managing from an
NMS
You can access your switch from a network management station (NMS), and then
configure and manage the switch through the switch’s management agent.
Simple network management protocol (SNMP) is applied between the NMS and
the agent. Refer to
“SNMP Configuration” on page 351 and “RMON
Configuration” on page 361 for related information.
To manage your switch from an NMS, you need to perform related configuration
on both the NMS and the switch.
