This example sets the bandwidth to 2000 kbps on a specic tunnel interface .
device# configure terminal
device(config)# interface tunnel 2
device(config-tnif-2)# tunnel mode gre ip
device(config-tnif-2)# tunnel source 10.0.0.1
device(config-tnif-2)# tunnel destination 10.10.0.1
device(config-tnif-2)# ip address 10.0.0.1/24
device(config-tnif-2)# bandwidth 2000
The bandwidth specied in this example results in the following OSPF interface costs, assuming the auto-cost is 100:
• OSPF Interface Cost for the Trunk Group is equal to ((100 * 1000) + (2000 - 1)÷ 2000) = 50
• OSPF Interface Cost for the GRE/IPv6 tunnel is equal to ((100 * 1000) + (2000 - 1)÷ 2000) = 50
Displaying IP conguration information and statistics
The following sections describe IP display options for Layer 3 switches and Layer 2 switches.
Changing the network mask display to prex format
By default, the CLI displays network masks in classical IP address format (example: 255.255.255.0). You can change the displays to
prex format (example: /18) on a Layer 3 switch or Layer 2 switch using the following CLI method.
NOTE
This option does not aect how information is displayed in the Web Management
Interface.
To enable CIDR format for displaying network masks, entering the following command at the global CONFIG level of the CLI.
device(config)# ip show-subnet-length
Syntax: [no] ip show-subnet-length
Displaying IP information - Layer 3 switches
You can display the following IP conguration information statistics on Layer 3 switches:
• Global IP parameter settings and IP access policies
• CPU utilization statistics
• IP interfaces
• ARP entries
• Static ARP entries
• IP forwarding cache
• IP route table
• IP trac statistics
