Dell PowerSwitch S4820T Configuration Guide for the S4820T System 9.100.0 - Page 592

• seconds: the range is from 1 to 65535 (the default is 10 seconds). The hello interval must be the same on all routers in the OSPF network. • Use the MD5 algorithm to produce a message digest or key, which is sent instead of the key. CONFIG-INTERFACE mode ip ospf message-digest-key keyid md5 key • keyid: the range is from 1 to 255. • Key: a character string. NOTE: Be sure to write down or otherwise record the key. You cannot learn the key after it is configured. You must be careful when changing this key. NOTE: You can configure a maximum of six digest keys on an interface. Of the available six digest keys, the switches select the MD5 key that is common. The remaining MD5 keys are unused. • Change the priority of the interface, which is used to determine the Designated Router for the OSPF broadcast network. CONFIG-INTERFACE mode ip ospf priority number • number: the range is from 0 to 255 (the default is 1). • Change the retransmission interval between LSAs. CONFIG-INTERFACE mode ip ospf retransmit-interval seconds • seconds: the range is from 1 to 65535 (the default is 5 seconds). The retransmit interval must be the same on all routers in the OSPF network. • Change the wait period between link state update packets sent out the interface. CONFIG-INTERFACE mode ip ospf transmit-delay seconds • seconds: the range is from 1 to 65535 (the default is 1 second). The transmit delay must be the same on all routers in the OSPF network. Example of Changing and Verifying the cost Parameter and Viewing Interface Status To view interface configurations, use the show config command in CONFIGURATION INTERFACE mode. To view interface status in the OSPF process, use the show ip ospf interface command in EXEC mode. The bold lines in the example show the change on the interface. The change is reflected in the OSPF configuration.
