Chapter 20 Show Commands

show fspf

show fspf

To display global FSPF information, use the show fspf command. This information includes:

the domain number of the switch

the autonomous region for the switch

Min_LS_arrival: the minimum time that must elapse before the switch accepts LSR updates

Min_LS_interval: the minimum time that must elapse before the switch can transmit an LSR

LS_refresh_time: the interval lapse between refresh LSR transmissions

Max_age: the maximum time aa LSR can stay before being deleted

show fspf [database [vsan vsan-id[domain domain-id] [detail]] interface vsan vsan-id[interface [interface-range]]]

Syntax Description

 

database

To display information of fspf database for a VSAN. If no other parameters

 

 

 

 

 

 

 

are given all the LSRs in the database are displayed. If more specific

 

 

 

 

 

 

 

information is required then the domain number of the owner of the LSR

 

 

 

 

 

 

 

may be given. Detail gives more detailed information on each LSR.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

vsan vsan-id

Specifies the VSAN ID. The range is 1 to 4093.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

domain domain-id

The domain of the database. The parameter domain_num is unsigned

 

 

 

 

 

 

 

integers in the range 0-255.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

detail

Displays detailed FSPF information for the VSAN.

 

 

 

 

 

 

 

 

 

 

 

 

 

interface interface-rangeDisplay FSPF interface information for a given VSAN. If the interface

 

 

 

 

 

 

 

number is specified information on the neighbor on that interface is

 

 

 

 

 

 

 

displayed. If no interface is specified information on all interfaces are

 

 

 

 

 

 

 

displayed. The parameter interface-rangeis of the format fcslot/port -

 

 

 

 

 

 

 

fcslot/port.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Defaults
