We have on our switches VLAN's for data and telephony. All locations are connected switch to switch with fiber except for one location, we have a leased line connectec with two 1600 cisco routers. Now this has IOS release 12.0 or so. Vlan is only possible for :The following Cisco routers support the Extended VLAN ID feature:
â¢Cisco 800 series routers, including models 851, 857, 871, 876, 877, 878
â¢Cisco 1700 series routers, including models 1711, 1712, 1751, 1751V, 1760
â¢Cisco 1800 series routers, including models 1801, 1802, 1803, 1811, 1812, 1841
â¢Cisco 2600 series routers, including models 2610XM, 2611XM, 2620XM, 2621XM, 2650XM, 2651XM, 2691
â¢Cisco 2800 series routers, including models 2801, 2811, 2821, 2851
Vlan is possible since IOS release 12.4.
Would it work if I upgrade the 1600's with this IOS or is it just hardware that it is dependent from?
Or is their an alternative way to seperate this telephony en data traffic with both other ranges?
Yes, on the routers because it's a leased line and the router cannot do the trick without it.
I figgered it out myself, it's not possible with the router, or you should use proxyARP routing on the telephony network but it won't work because the telephones do a ftp to the telephonecentral to get IP from DHCP tel.central. Bridging is also not an option I guess because with the VLAN situations and you also cannot use tagging for this other problem than. als Qos is not available then , so best option is two new routers I guess.
