Switch to adsl modem


I cannot understand how there is communication between a 2950 switch on port 0/8 to an adsl mode. I have configured the port to ba an access port on vlan 2 and did not configure the ISP adsl modem/router.

I went to telnet the dsl/router and found out that it has only the desault vlan 1 set.

can someone explain why there is ping between them and internet works for all pcs connected to the switch

Thank you

Re: Switch to adsl modem

I now also set the same switchport which is going the dsl modem to  vlan 3 and again all pcs on vlan 3 can ping the modem, this is not supposed to happen right since the modem does not know about vlan 3


Re: Switch to adsl modem

  The vlan number means nothing unless you are running a trunk link to a device , then the switch will tag the packets  with a vlan id .  As long as its a access port going to the device it can be any vlan number you want , you just can't have multiple vlans on the switch and expect them all to talk to the dsl modem . So yes any pc would be able to ping the device .
