Hello Group,
I dont' know if anyone found this yet, but I couldn't find an
errata on the ciscopress homepage so here it goes. On Pg .100 it states
that a VLAN ID header is 10 bits long in the first 26 bytes of the ISL
encapulation. But later in Figure 3-7 it says the VLAN ID field is 15
bits. Can someone clarify this for me?
Another issue is on Pg 104 is says original ethernet frames can't exceed
1518 bytes. But they state that if using 802.1q the frame becomes 1522
bytes long. I thought 802.1q inserts it's information into the exsisting
ethernet frame and ISL encapulates it making the size of the frame 1522
bytes. Can someone also clarify this of me?
Thanks in advance
