Parameter Description
CLI Configuration
DynamicProxy This parameter allows you to enable or disable the
dynamic proxy for RADIUS and Terminal Access
Controller Access Control System (TACACS)servers.
l Dynamic RADIUS proxy—When dynamic
RADIUSproxy is enabled, the VC network will use
the IP address of the VC for communication with
external RADIUS servers. Ensure that you set the
VC IP address as a Network Access Server (NAS)
client in the RADIUS server if Dynamic RADIUS
proxy is enabled.
l Dynamic TACACSproxy—When enabled, the VC
network will use the IP address of the VC for
communication with external TACACS servers.
The IP address is chosen based on one of the
following rules:
If a VPNtunnel exists between the W-IAP and the
TACACS server, then the IP address of the tunnel
interface will be used.
If a VC IPaddress is configured, the the same will be
used by the VC network to communicate with the
external TACACSserver.
If a VC IPis not configured, then the IP address of the
bridge interface is used.
NOTE: When dynamic-tacacs-proxy is enabled on
the W-IAP, the TACACSserver cannot identify the
slave W-IAP that generates the TACACStraffic as
the source IP address is changed.
To enable dynamic
RADIUS proxy:
(Instant AP)(config)
# dynamic-radius-
proxy
To enable TACACS proxy:
(Instant AP)(config)
# dynamic-tacacs-
proxy
NTPServer
This parameter allows you to configure NTP server.
To facilitate communication between various
elements in a network, time synchronization
between the elements and across the network is
critical. Time synchronization allows you to:
l Trace and track security gaps, monitor network
usage, and troubleshoot network issues.
l Validate certificates.
l Map an event on one network element to a
corresponding event on another.
l Maintain accurate time for billing services and
similar tasks.
To configure an NTP
server:
(Instant AP)(config)
# ntp-server <name>
