Tracert Trill - HPE FlexFabric 5930 Series Command Reference Manual

minimum-interval: Specifies the minimum SPF calculation interval in the range of 10 to 60000
milliseconds. The value must be a multiple of 10 and smaller than the maximum SPF calculation
interval.
incremental-interval: Specifies the SPF calculation incremental interval in the range of 10 to 60000
milliseconds. The value must be a multiple of 10 and smaller than the maximum SPF calculation
interval.
Usage guidelines
The RB uses the SPF algorithm to calculate a shortest path tree with itself as the root based on the
local LSDB. The RB determines the next hop according to the shortest path tree.
By adjusting the SPF calculation parameters, you can prevent frequent network changes from
consuming an excessive amount of bandwidth and device resources.
When the network is stable, the SPF calculation interval for continuous calculations is reduced to
minimum-interval. When the network is unstable, the SPF calculation interval is added by
incremental-interval × 2
calculation until the maximum interval is reached.
Examples
# Set the maximum SPF calculation interval to 15 seconds, the minimum SPF calculation interval to
100 milliseconds, and the incremental interval to 200 milliseconds.

Parameters
-f first-ttl: Specifies the TTL value of the first packet sent to the destination. The value range is 0 to 63,
and the default value is 0. This TTL cannot be greater than the value of the max-ttl argument.
-i interface-type interface-number: Specifies the source interface for OAM echo requests. If you do
not specify this option when multiple equal-cost routes to the destination exist, the system uses the
first egress interface as the source interface.
-m max-ttl: Specifies the maximum TTL allowed for an echo request. The value range is 0 to 63, and
the default value is 63. This TTL cannot be smaller than the value of the first-ttl argument.
-priority priority: Specifies the 802.1p priority in the inner Ethernet header of the OAM echo request.
The value range is 0 to 7, and the default value is 0. A higher value indicates a higher priority.
-q packet-number: Specifies the number of requests to send per hop. The value range is 1 to 10, and
the default value is 3.
-t timeout: Specifies the timeout time of an OAM echo reply. The value range is 0 to 65535
milliseconds, and the default value is 2000 milliseconds. If the source does not receive an OAM echo
reply within the timeout, it considers the OAM echo reply times out.
