DLP- A547 Edit an IP-Over-CLNS Tunnel
Step2 Choose the subnet you want to edit, then click Edit.
Step3 In the Edit <subnet type> Subnet <slot/port> dialog box, edit the following fields:
•ESH—The End System Hello PDU propagation frequency. An end system NE transmits ESHs to
inform other ESs and ISs about the NSAPs it serves. The default is 10 seconds. The range is 10 to
1000 seconds.
•ISH—The Intermediate System Hello PDU propagation frequency. An intermediate system NE
sends ISHs to other ESs and ISs to inform them about the NETs it serves. The default is 10 seconds.
The range is 10 to 1000 seconds.
•IIH—The Intermediate System to Intermediate System Hello PDU propagation frequency. The IS-IS
Hello PDUs establish and maintain adjacencies between ISs. The default is 3 seconds. The range is
1 to 600 seconds.
Note The IS-IS Cost and DIS Priority parameters are provisioned when you create or enable a
subnet. You cannot change the parameters after the subnet is created. To change the DIS
Priority and IS-IS Cost parameters, delete the subnet and create a new one.
Click OK.
Step4 Return to your originating procedure (NTP).
DLP-A547 Edit an IP-Over-CLNS Tunnel
Caution Changing the IP or NSAP addresses or an IP-over-CLNS tunnel can cause loss of NE visibility or NE
isolation. Do not change network addresses until you verify the changes with your network
administrator.
Step1 In node view, click the Provisioning > OSI > Tunnels tabs.
Step2 Click Edit.
Step3 In the Edit IP Over OSI Tunnel dialog box, complete the following fields:
•Tunnel Type—Choose a tunnel type:
–
Cisco—Creates the proprietary Cisco IP tunnel. Cisco IP tunnels add the CLNS header to the
IP packets.
–
GRE—Creates a Generic Routing Encapsulation tunnel. GRE tunnels add the CLNS header and
a GRE header to the IP packets.
Purpose This task allows you to edit the parameters of an IP-over-CLNS tunnel.
