R3303-HP 6600/HSR6600 Routers Layer 3 - IP Services Command Reference

291
Default command level
2: System level
Parameters
number: Specifies the tunnel interface number.
Usage guidelines
If you want to observe new traffic statistics on a tunnel interface, you can use this command to clear old
statistics:
• If you do not specify any parameters, this command clears the statistics for all interfaces.
• If you specify only the tunnel keyword, this command clears the statistics for all tunnel interfaces.
• If you specify both the tunnel keyword and the number argument, this command clears the statistics
for the specified tunnel interface.
Examples
# Clear the statistics for the interface Tunnel 3.
<Sysname> reset counters interface tunnel 3
service
Use service to specify the service card for forwarding the traffic on the current tunnel interface.
Use undo service to restore the default.
Syntax
service slot slot-number
undo service slot
Default
No service card is specified for the tunnel interface.
Views
Tunnel interface view
Default command level
2: System level
Parameters
slot slot-number: Specifies the number of the slot where a card resides.
Usage guidelines
If no service card is specified for forwarding the traffic on the current interface, a GRE, IPv4 over IPv4, or
IPv4 over IPv6 tunnel automatically selects a service card. If the specified source interface is a virtual
interface such as loopback interface and virtual template interface, or no source interface is specified
and the outbound interface of the route to the destination address is a virtual interface, the GRE, IPv4
over IPv4, or IPv4 over IPv6 tunnel uses the main board for processing traffic on the current tunnel
interface. To prevent overload on the main board in such cases, specify the service card for forwarding
the traffic on the tunnel interface by using the service command.
If you remove the specified service card, traffic on the tunnel interface cannot be forwarded even if the
tunnel interface is up. After you insert the service card, traffic forwarding recovers.
