Configuring Tunnel-Server Ports and Tunnel-Service Interfaces

This section describes the tasks associated with configuring a tunnel-server port and tunnel-service interface.

Note: Dedicated and shared tunnel servers do not support QoS profiles on interfaces stacked on the server-port.

Identifying the Physical Location of the Tunnel-Server Port

To display the physical location of the dedicated and shared tunnel-server ports on your module, issue the show tunnel-server config command.

host1#show tunnel-server config

   

                       Server Ports
                          ------------
                                         Provisioned
  Port      Type     MaximumInterfaces   Interfaces    HwPresent     Bandwidth-Reserved
--------   -------   -----------------   -----------   ---------     ----------------- 
Port 2/2/0   shared       8000                0             yes		   	N/A
Port 8/0/0   dedicated    16000               8000          yes		   	N/A
Port 12/2/0  shared       8000                0             yes		   	90

Provisioning the Maximum Number of Interfaces on a Tunnel-Server
Port
To provision the maximum number of interfaces on
a tunnel-server port:
  1.  From Global Configuration mode, specify the location
of the dedicated tunnel-server port that you want to configure.
    On a dedicated tunnel-server port:
    host1(config)#tunnel-server 8/0/0 host1(config-tunnel-server)#
    On a shared tunnel-server port:
    host1(config)#tunnel-server 2/2/0 host1(config-tunnel-server)#
    This command accesses Tunnel Server Configuration
mode.
    Note:
			When you issue the tunnel-server command,
ensure that you specify the same interface specifier that was displayed
for this tunnel-server port in the show  tunnel-server config command in the output
described in Identifying the Physical Location of the Tunnel-Server Port. If you specify an incorrect
location for the tunnel-server port, the router displays an error
message and rejects the command as invalid.
  2. Provision the maximum number of tunnel-service interfaces
to be used on the dedicated tunnel-server port.
    host1(config-tunnel-server)#max-interfaces
all-available 
Note:
			When you enable shared tunnel server on the ES2 10G ADV LM,
it reloads with a warning message and then the image specific to shared
tunnel server appears.
Reserving Bandwidth on Shared Tunnel-Server Ports
To reserve a certain percentage of the total bandwidth for forwarding
on a shared tunnel-server port:
Note:
			When you direct the router to reserve a percentage of the total
bandwidth for forwarding, you may not always obtain the exact percentage
of bandwidth specified. Because of the overhead involved with identifying
and assigning incoming traffic to the appropriate resources, you may
obtain a value less than the configured value. For instance, if you
reserve 50 percent of the total bandwidth for forwarding, you will
not obtain an actual bandwidth of 5 Gbps for forwarding and 5 Gbps
for tunnel processing.
  1. From Global Configuration mode, specify the location of
the shared tunnel-server port that you want to configure.
    host1(config)#tunnel-server 2/2/0 host1(config-tunnel-server)#
    This command accesses Tunnel Server Configuration
mode.
    Note:
			When you issue the tunnel-server command,
ensure that you specify the same interface specifier that was displayed
for this tunnel-server port in the show  tunnel-server config command in the output
described in Identifying the Physical Location of the Tunnel-Server Port. If you specify an incorrect
location for the tunnel-server port, the router displays an error
message and rejects the command as invalid.
  2. Reserve the percentage of bandwidth to be used for forwarding
on the shared tunnel-server port.
    host1(config-tunnel-server)#reserve-bandwidth
80 
Note:
			This command is supported only on the ES2 10G ADV LM when configured
in shared server mode. It is not supported on other line modules that
support tunnel configuration. 
Verifying the Tunnel-Server Interface Configuration
To verify that you properly provisioned the number
of tunnel-server interfaces or reserved a percentage of the total
bandwidth on the tunnel-server port:
  1. From Tunnel Server Configuration Mode, return to Privileged
Exec mode.
    host1(config-tunnel-server)#exit host1(config)#exit host1#
  2. Issue the show tunnel-server config command.
    host1#show tunnel-server config

     

                         Server Ports
                          ------------
                                         Provisioned
  Port      Type     MaximumInterfaces   Interfaces    HwPresent	Bandwidth-Reserved 
--------   -------   -----------------   -----------   ---------	----------------- 
Port 2/2/0   shared       8000                5000          yes				80
Port 8/0/0   dedicated    16000          all-available 				 yes     N/A
Port 12/0/0  shared       8000                0					   		   yes      	N/A

    For more information about using the show tunnel-server command, see Monitoring Tunnel-Service Interfaces.
Unprovisioning Tunnel-Service Interfaces
To unprovision the tunnel-service interfaces on
a tunnel-server port, use any of the following commands, all of which
have the same effect:
Note:
			When you issue these commands on the ES2 10G ADV LM, the line
module reloads with a warning message and the original forwarding
image appears.
max-interfaces
reserve-bandwidth
tunnel-server
