On what VLAN interface do you have the IP address configured on the
switch, VLAN10? The default is VLAN1 and if you haven't changed that,
the switch management ip address will not be able to communicate with
the outside world. In that situation, the switch 10.1.1.0/24 network is
on VLAN1, the default management VLAN, but the router has that subnet
configured on VLAN10.
I've missed most of this thread so forgive me if you've already covered
this, but this configuration error would cause the problems you're
seeing.

Hi Luke,
Here is the config:
1912: #ip addr 10.1.1.2 255.255.255.0
#ip default-gateway 10.1.1.1
2620: #int f0/0
#no ip addr
#exit
#int f0/0.10
#encap isl 10
#ip addr 10.1.1.1 255.255.255.0
#shut
#no shut
#int f0/0.20
#encap isl 20
#ip addr 20.1.1.1 255.255.255.0
#shut
#no shut
#end
And so on for 30.1.1.1, 40.1.1.1.......till 80.1.1.1
1st pc ip=10.1.1.10, 255.255.255.0, 10.1.1.1
2nd pc ip=20.1.1.10, 255.255.255.0, 20.1.1.1
And so on till 80.1.1.10, 255.255.255.0, 80.1.1.1
All the pc's are plugged into the 1912. The router is plugged into
f0/26.
All pc's can ping one another and the router and ditto from the router
back
to each pc. Same for telnet from a pc to the router. NO problem.
*** But CANNOT ping the switch from the pc or the router no can ping
the
swich ip on the switch itself or the router or any pc *** This is the
problem.
Please advise.
Thank you.
