• Question 52:

  What is required for a LAN switch to support 802.1q Q-in-Q encapsulation?

  A. Support less than 1500 MTU
  B. Support 1504 MTU or higher
  C. Support 1522 layer 3 IP and IPX packet
  D. Support 1547 MTU only
  B. Support 1504 MTU or higher

  ---

  The default system MTU for traffic on Catalyst switches is 1500 bytes. Because the 802.1Q tunneling (Q- in-Q) feature increases the frame size by 4 bytes when the extra tag is added, you must configure all switches in the service-provider network to be able to process maximum frames by increasing the switch system MTU size to at least 1504 bytes. http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.1_13_ea1/confi guration/ guide/swtunnel.html
