•Is Telnet enabled or disabled by default on the WLSE?
•Can SSH be disabled?, page 1-2
•Can I run a job to convert a number of access points from non-IOS to IOS?
•What are the requirements for WLSE usernames and passwords?
Q.
Can several users be logged on and managing the same access point at once?
A.
Yes, several users can view data and reports on the same access point. More
than one user can create configuration and firmware update jobs for the same
access point and these will be run in the order they are scheduled.
Configuration templates may be modified by more than one user at the same
time and the last write will overwrite the others.
Q.
What ports and protocols does the WLSE use?
A.
For discovery and fault monitoring, the WLSE primarily uses SNMP (UDP
port 161). For applying configuration changes, the WLSE uses SNMP, HTTP
(TCP port 80 or as configured), and TFTP (UDP port 69).
Q.
Can I use a different HTTP port to manage the access point?
A.
Yes, the HTTP port can be changed on the access point. The change will be
reflected in WLSE after the next inventory cycle, or if you choose to ru n
inventory now for the devices on which HTTP port was changed. This is
assuming the inventory is done by SNMP and not HTTP.
Q.
Is Telnet enabled or disabled by default on the WLSE?
A.
Telnet is disabled by default for security reasons. SSH is enabled by default.
Q.
Can SSH be disabled?
A.
It cannot be disabled on the WLSE itself, but you can use the firewall
command to deny all SSH connections. For example, the following CLI
command will cause the WLSE to reject all incoming SSH connections on the
Ethernet 0 interface but allows connections through other protocols and other
ports:
firewall ethernet0 private firewall ethernet0 private ssh
