Modify Tunnel Hop Limits for a Specific Tunnel
Modify tunnel hop limits to update hop-limit values on previously configured tunnels.
Use this procedure to modify the hop limits for a specific tunnel interface.
About this task
The tunnel hop limit configures the value of the time-to-live (TTL) for IPv4 packets.
Procedure
- In the navigation pane, expand .
- Select Tunnel.
- Select the Tunnel Config tab.
- Select the tunnel row.
- Select Tunnel Interface.
- Double-click the HopLimit value to modify the information as required.
- Select Apply.
Tunnel Interface Field Descriptions
Use the data in the following table to use the Tunnel Interface tab.
Name | Description |
---|---|
Index | Identifies the tunnel interface internally. The value is derived from the tunnel ID. |
EncapsMethod | Displays the encapsulation method for the tunnel: manual for manually configured tunnels and 6to4 for automatically configured tunnels. |
HopLimit | Configures the maximum number of hops in the tunnel. The default value is 255. |
Security | Indicates the type of security on the tunnel interface. |
TOS | Displays the method used to configure the high 6 bits (the differentiated services codepoint) of the IPv4 type of service (TOS) or IPv6 traffic class in the outer IP header. A value of -1 indicates that the bits are copied from the payload header. A value of -2 indicates that a traffic conditioner is invoked and more information can be available in a traffic conditioner MIB module. A value from 0 to 63 indicates that the bit field is configured to the indicated value. |
FlowLabel | Displays the method used to configure the IPv6 flow label value. This object is not required where AddressType indicates the tunnel is not over IPv6. A value of -1 indicates that a traffic conditioner is invoked and more information can be available in a traffic conditioner MIB. Any other value indicates that the flow label field is configured to the indicated value. |
AddressType | Displays manual for a manually configured tunnel, or sixToFour for autoconfigured tunnels. |
LocalInetAddress | Identifies the local endpoint address of the tunnel. |
RemoteInetAddress | Identifies the remote endpoint of the tunnel. |
EncapsLimit | Displays the maximum number of additional encapsulations permitted for packets undergoing encapsulation at this node. A value of -1 indicates that no limit exists, except as a result of the packet size. |
