Chapter 3. Ethernet switch interoperability 47
We use the same Cisco 2924-XL switch, but change to an IBM 8275-225, so
both switches support IEEE 802.1Q trunking.
In this test we will focus on the security between VLANs, tagging frames for
trunking VLAN, and the VLAN trunk itself.
Figure 26. Lab 2, physical connections and VLANs
Figure 26 shows the physical connections and the VLAN ports for lab 2. We
use VLANs 42 and 83 over the trunk. VLAN 1 is the default.
