BROCADE IP PRIMER

Chapter 7: Link Aggregation (Trunks)9. I have two chassis switches, each with multiple blades. May I set up atrunk between these two switches and have the trunk ports span multipleblades?a. No, ports must be contiguous.b. No, you can only do that with a Server Trunk.c. Yes, as long as each blade houses two or four ports of the trunk.d. Yes, because of LACP.10. When a trunk is load balancing Layer 3 (IP) traffic, what criteria does ituse to decide which trunk interface to send the traffic?a. Source IP, Destination IP, Source MAC, Destination MAC, Protocolb. Packet sizec. Destination MACd. Destination IPAnswers to Review Questions1. b. For 8-port (and potentially larger), you need a chassis.2. c. 9 is correct. Remember to divide the last interface number (12, in thiscase) by four. If it's a round number (no remainder or fraction), it's correct.3. d. Dynamic trunks allow you to add or subtract interfaces from the trunkwithout removing the entire trunk.4. a. LACPDU's are the frames that are passed between LACP links. BPDU'swill be talked about in Chapter 8. The other two don't exist.5. c. Destination MAC. If it's strictly Layer 2 traffic, it's not going to have anyIP information. It will just have a Source and Destination MAC address. Itload balances on the Destination MAC address.6. b. trunk deploy. If you forget, the switch will remind you immediately followinga command that requires it.7. b. The server per-packet load balancing sends frames round-robin acrossall links.8. c. Keys can be configured to distinguish one LACP trunk from another.9. c. You can span multiple blades, but you've got to have at least a four-porttrunk (two-ports per blade), and the blades must be sequential, and youmust start on an odd numbered slot.10. a. With Layer 3 traffic, it uses all of these criteria to decide which trunkinterface to direct traffic through.168 Brocade IP Primer
