I started reading the ICND book and in that book i found that 2950 support ISL according to the configuration, however I open my Sybex and it's telling me that 2950 only support 802.1q and you cannot combine or use both as a trunking protocol.
for example : a 2950 SW to a
let say 5 1900 SW running ISL as a trunking protocol is this possible?

From everything I've read the 2950 supports only dot1q and 1900 only support ISL so trunking between the two is not possible.
Hopefully someone else can confirm this. -

Did you read the ICND book chapter 3 VLAN, I don't know why the author used the 2950 sw and 1900.
