HP VPN Firewall Appliances Network Management Command Reference

424
level-1: Specifies the interval for sending Level-1 hello packets.
level-2: Specifies the interval for sending Level-2 hello packets.
Usage guidelines
Level-1 and Level-2 hello packets are sent independently on a broadcast network, so you need to specify
an interval for each of the two levels. On a P2P link, Level-1 and Level-2 packets are both sent in P2P hello
packets, and you need not specify an interval for each of the two levels.
You can configure keywords level-1 and level-2 only on broadcast interfaces. Before you do that, enable
IS-IS on the interface.
As the shorter the interval is, the more system resources are occupied, you should configure a proper
interval as needed.
If no level is specified, the hello interval applies to both Level-1 and Level-2.
Examples
# Configure Level-2 hello packets to be sent every 20 seconds over GigabitEthernet 1/1.
<Sysname> system-view
[Sysname] interface GigabitEthernet 1/1
[Sysname-GigabitEthernet1/1] isis timer hello 20 level-2
