R21xx-HP FlexFabric 11900 TRILL Command Reference

27
Usage guidelines
The adjacency holding time is obtained by multiplying the Hello interval by the Hello multiplier. The RB
advertises the adjacency holding time to neighbors through Hello frames. If a neighbor does not receive
any Hello frame from the RB before the adjacency holding time expires, it removes the TRILL adjacency
with the RB.
The product of the Hello interval and the Hello multiplier cannot exceed 65535.
Configuration in Layer 2 Ethernet interface view takes effect on only the current port. Configuration in
Layer 2 aggregate interface view takes effect on the current interface and its member ports.
Configuration on the member port of an aggregate interface takes effect after the member port leaves the
aggregation group.
Examples
# Set the number of invalid Hello frames to 6 on Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] trill timer holding-multiplier 6
Related commands
trill timer hello
trill timer lsp
Use trill timer lsp to configure the minimum LSP interval and the maximum number of LSPs transmitted per
time.
Use undo trill timer lsp to restore the default.
Syntax
trill timer lsp interval [ count count ]
undo trill timer lsp
Default
The minimum LSP interval is 10 milliseconds, and the maximum number of LSPs transmitted per time is 5.

Parameters
interval: Specifies the minimum LSP interval, which is in the range of 10 to 1000 milliseconds. The
interval argument is in increments of 10 milliseconds.
count: Specifies the maximum number of LSPs transmitted per time, which is in the range of 1 to 1000.
Usage guidelines
To avoid frequent LSP aging in the network, RBs periodically advertise LSPs. The actual refresh interval of
an LSP is determined by both the minimum LSP interval and the maximum number of LSPs transmitted per
time. To prevent LSPs from being aged out accidentally, set the LSP maximum age and the LSP refresh
interval appropriately.
