www.qtech.ru

1.2.44 tunnel destination

 This command is not supported by this switch.

1.2.45 tunnel nexthop

 This command is not supported by this switch.

1.2.46 tunnel 6to4-relay

 This command is not supported by the switch.

1.2.47 tunnel mode

 This command is not supported by this switch.

1.3 Commands for IP Route Aggregation

1.3.1 ip fib optimize

 Command: ip fib optimize

 no ip fib optimize

 Function: Enables the switch to use optimized IP route aggregation algorithm; the “no

ip fib optimize” disables the optimized IP route aggregation algorithm.

 Default: Optimized IP route aggregation algorithm is disabled by default.

 Command mode: Global Mode.

 Usage Guide: This command is used to optimize the aggregation algorithm: if the route

table contains no default route, the next hop most frequently referred to will be used

to construct a virtual default route to simplify the aggregation result. This method has

the benefit of more effectively simplifying the aggregation result. However, while

adding a virtual default route to the chip segment route table reduces CPU load, it may

introduce unnecessary data stream to switches of the next hop. In fact, part of local

switch CPU load is transferred to switches of the next hop.

 Example: Disabling optimized IP route aggregation algorithm.

 Switch(config)# no ip fib optimize

1.4 Commands for ARP Configuration

1.4.1 arp

 Command: arp <ip_address> <mac_address> {interface [ethernet] <portName>}

 no arp <ip_address>

 Function: Configures a static ARP entry; the “no arp <ip_address>” command deletes a

ARP entry of the specified IP address.
