[c-nsp] need help on switch configuration

[Raj Panchal]

Where is ur router connected which port ? 
Is ur router doing intervlan routing ?
Which port is ur second switch connected on the first switch ? Is it trunk ?
Is it trunking both the vlans ? Also both the vlans should be there in the
vlan database of both switches

Also check whether ur getting appropriate mac address in appropriate vlans
on the switch connected to ur router and switch connected to ur PCs in
question.

Hi All:

I have two switches and they are connected via
crossover cable. now i have two vlans (100 and 110)
configured and one works fine. but another just
doesn't work, meaning that it just doesn't pass
trafifc. this vlan is 192168.8.0/27; the servers, the
router interface (gateway) just don't talk to each
other. here is the configure:

what did I miss? trunk port 23 seems to work fine and
I ahve no problem to access network 10.10.100.0/27,
not trunk link 110 (port 24). tried different ports
and the results were the same:

globalnet-jsa#ping 192.168.8.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.8.1, timeout
is 2 seconds:
UUUUU
Success rate is 0 percent (0/5)
sw0-4200-oam#ping 10.10.100.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.10.100.1, timeout
is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip
min/avg/max = 1/5/16 ms
