tunnel-type

Configures the source IP (with mask), tunnel-type and tunnel-ID for the packets to be terminated.

Syntax

tunnel-type [ gre | erspan ] [ src-ip ipaddr | mask mask ] [tunnel-id value ]

no tunnel-type [ gre | erspan ] [ src-ip ipaddr |mask mask ] [tunnel-id value ]

Parameters

gre | erspan: Specifies the type of tunnel to be terminated.
src-ip ipaddr: Specifies the Source IP to be matched.
mask mask: Specifies the IP address mask.
tunnel-id value: Specifies the tunnel ID of the tunnel.

Modes

Transport tunnel config mode

Usage Guidelines

If all parameters match along with destination MAC in chassis MAC range, packets are terminated and relevant SAP ID is attached to the packets.

Validations for the command are as follows:

Valid tunnel type is provided.
Valid IP address and mask are provided.
Tunnel ID value is within allowed range.
Only one traffic type per ingress group is allowed.
The configured traffic type must be removed before configuring a new traffic type.
If the same command is executed more than once, the second and subsequent executions are ignored and no error is reported.
If the [no] form of the command is run without the configuration, the command is ignored and no error is reported.

Table 1. Error messages
Message	Reason
`Error: Tunnel type is already configured`	Only on of each tunnel type can be configured per ingress group. Valid types are GRE or ERSPAN.
`Error: Source IP address mask is already configured`
`Error: Deny IP address is already configured`
`Error: Source IP address conflicts with transport-tunnel name` `Error: Destination IP address conflicts with transport-tunnelname`	Source or destination transport-tunnels IP cannot overlap.
`Error: Invalid destination IP address` `Error: Invalid source IP address`	Reserved or poorly formed IP address entered.
`Error: Cannot add/modify source IP address of existing tunnel type`	Attempt to add source IP address and mask to existing tunnel type.

Examples

The following example configures the transport tunnel, tunnel-1.

Device(config)# transport-tunnel tunnel-1 
device(config-trs-tnl-tunnel-1)# tunnel-type erspan src-ip 10.10.10.0 mask 255.255.255.0 tunnel-id 12345
