Link of slave switch dead after reboot of master switch
We have the following setup:
SPECmaster_switch>slave_switch->SPEC
both switches:
PCB:3.30, FPGA:LX240T; version: v4.2 (Grzegorz Daniluk); compiled at Aug
28 2015 15:05:21
what we did:
1. had a working system with VLANs set on master_switch (probably
irrelevant)
2. the link between master_switch and slave_switch was unplugged, and
then plugged back
I cannot tell whether at this point it went back to life, since the
slave_switch is at different location)
3. the system did not work properly, probably because the SPEC did not
recover properly (different problem)
4. the master_switch was restarted and VLANs set, it did not help
5. we went to the location of the slave_switch and it turned out that
the link of slave_switch connected to the master_switch did not come
up (no leds)
6. re-plugging helped
