The following example shows that the appropriate ports on Switch Port 0 are forwarding:
RP/0/RP0/CPU0:router# show controllers switch 0 ports location 0/RP1/CPU0
Ports Active on Switch 0
FE Port 0 : Up, STP State : FORWARDING (Connects to - 0/RP0)
FE Port 1 : Up, STP State : FORWARDING (Connects to - 0/RP1)
FE Port 2 : Up, STP State : FORWARDING (Connects to - 0/SM0)
FE Port 3 : Up, STP State : FORWARDING (Connects to - 0/SM1)
FE Port 4 : Up, STP State : FORWARDING (Connects to - 0/SM2)
FE Port 5 : Up, STP State : FORWARDING (Connects to - 0/SM3)
FE Port 6 : Down (Connects to - )
FE Port 7 : Down (Connects to - )
FE Port 8 : Down (Connects to - 0/LC0)
FE Port 9 : Up, STP State : FORWARDING (Connects to - 0/LC1)
FE Port 10 : Down (Connects to - 0/LC2)
FE Port 11 : Up, STP State : FORWARDING (Connects to - 0/LC3)
FE Port 12 : Down (Connects to - 0/LC4)
FE Port 13 : Down (Connects to - 0/LC5)
FE Port 14 : Up, STP State : FORWARDING (Connects to - 0/LC6)
FE Port 15 : Down (Connects to - 0/LC7)
GE Port 0 : Down (Connects to - GE_0)
GE Port 1 : Down (Connects to - GE_1)
The following example shows the statistics for Switch Port 0:
Step 8
confreg 0x102
reset
Example:
rommon B2 > confreg 0x102
rommon B3 > reset
Exits ROMMON mode, resetting and initializing the router.
