DGS-3630 Series Layer 3 Stackable Managed Switch Web UI Reference Guide Parameter CSNP Interval Level-2 Hello Interval Level-1 Hello Interval Level-2 Hello Multiplier Level-1 Hello Multiplier Level-2 Metric Level-1 Metric Level-2 Password Level-1 Password Level-2 Priority Level-1 Priority Level-2 Wide Metric Level-1 Description Enter the time interval value between transmissions of level-2 CSNPs here. This interval only applies to the designated router. The range is from 1 to 65535 seconds. Select the Default option to use the default value. Enter the time interval value between transmissions of level-1 hello packets here. The range is from 1 to 65535 seconds. Select the Default option to use the default value. Enter the time interval value between transmissions of level-2 hello packets here. The range is from 1 to 65535 seconds. Select the Default option to use the default value. Enter the hello multiplier level-1 value here. The hello multiplier times the hello interval is equal to the hold time, which is advertised in ISIS hello packets. Using a smaller hello multiplier will get fast convergence. But it can result in more routing instability. When network stability is needed, set the hello multiplier to a larger value. The range is from 2 to 100. Select the Default option to use the default value. Enter the hello multiplier level-2 value here. The range is from 2 to 100. Select the Default option to use the default value. Enter the ISIS metric value here. This is assigned to the link and used to calculate the cost from each router via the links in the network to other destinations. This metric should be used only in the SPF calculation for Level 1 routing. The range is from 1 to 63. Select the Default option to use the default value. Enter the ISIS metric value here. This is assigned to the link and used to calculate the cost from each router via the links in the network to other destinations. This metric should be used only in the SPF calculation for Level 2 routing. The range is from 1 to 63. Select the Default option to use the default value. Enter the ISIS password used in level-1 routing here. This enables the prevention of unauthorized routers from forming adjacencies with this router, and thus protects the network from intruders. The password is exchanged as plain text and thus provides only limited security. This can be up to 16 characters long. Select the Default option to use the default setting. Enter the ISIS password used in level-2 routing here. This can be up to 16 characters long. Select the Default option to use the default setting. Enter the priority value of a Switch used in level-1 routing here. The priority is used to determine which router on a LAN will be the DIS. The priority is advertised in the hello packets. The device with the highest priority will become the DIS. In ISIS, there is no backup designated router. Setting the priority to 0 lowers the chance of this system becoming the DIS, but does not prevent it. If a system with a higher priority comes up, it will take over the role from the current DIS. In the case of equal priorities, the highest MAC address breaks the tie. The range is from 0 to 127. Select the Default option to use the default value. Enter the priority value of a Switch used in level-2 routing here. The range is from 0 to 127. Select the Default option to use the default value. Enter the wider metric value that is assigned to the link and used to calculate the cost from other routers via the links in the network to other destinations for level-1 routing here. The range is from 1 to 16777214. Select the Default option to use the default value. 404
