Parameter Description Range Default
<interval>
Number of seconds at which keepalive frames
are sent.
1-86400 10
seconds
<retries>
Number of consecutive times that the
keepalives fail before the tunnel is considered
to be down.
0-1024 3
<cisco>
The <cisco> option enables keepalive
interoperability for Layer-3 tunnels between
controllers and Cisco network devices. Dell
sets the keepalive packet’s GRE protocol field
to 0x801; however, Cisco sets the GRE protocol
field to 0. When this option is enabled, the Dell
controller automatically sets the GRE protocol
value to 0.
Disabled
source
The local endpoint of the tunnel on the
controller. This can be one of the following:
l <A.B.C.D>: Specify an IPv4 address.
l controller-ip: IPv4 address of the controller.
l loopback: Loopback interface configured on
the controller.
l vlan <vlanid>: Specify the VLAN interface
ID.
l ipv6: Specify one of the following IPv6
options:
n <X:X:X:X::X>: Specify the IPv6 address.
n controller-ip: IPv4 address of the
controller.
n loopback: IPv6 loopback interface
configured on the controller.
n vlan <vlan id>: Specify the VLAN
interface ID.
— —
vlan
Specifies the VLANs to be included in this
tunnel.
l <vlan id>
Specify the VLAN interface ID.
NOTE: You can configure a VLANonly if the
tunnel mode is set to Layer-2 (mode gre <16-
bit protocol number>). If the tunnel mode is not
set to Layer-2 mode, the system displays an
error message: Tunnel is an IP [v6]GRE Tunnel.
Change the mode before adding this.

Usage Guidelines
You can configure a Layer-2 or Layer-3 GRE tunnel between a Dell controller and another GRE-capable device.
The default is an IPv4 Layer-3 GRE tunnel (tunnel mode gre ip).
