Question Image

An engineer is implementing zoning on two Cisco MDS switches. After the implementation is complete, the E Ports connecting the two Cisco MDS switches become isolated.

What is incorrect in the implementation?

  • A Zones are local to the MDS switch and name service must be used to activate the connection between E Ports.
  • B Different zone set names must be configured on both MDS switches.
  • C Zones must have the same name on both MDS switches for the E Ports to function.
  • D E Ports on both MDS switches must be configured as F Ports for the zoning to function.
Explanation

Zones that span Cisco MDS switches must use the same zone name and matching membership on each switch. Switch-specific zone names such as A1 versus A2 and B1 versus B2 do not form consistent cross-switch zones; the resulting zoning mismatch can isolate the E Ports during fabric merge. Cisco documents that E Ports can isolate when active zoning databases conflict and that identically named zones must have identical members.
