Peoplez,
I commented on this before, and I was very confident about my answer (that
you always use non-canonical mac address in any of your dlsw statements).
But I look at the CCIE_CRAMsheet.doc that some people got from somewhere,
and now I'm confused, because it looks like that the source of the document
might be valid.
"Ethernet-----Traffic that originates on Ethernet is picked up from the
local Ethernet bridge group and transported across the DLSw network. DLSw
always transfers data in noncanonical format. DLSw will automatically make
the correct MAC address conversion depending on the destination media. When
DLSw+ receives a MAC address from an Ethernet-attached device, it assumes it
is canonical and converts it to noncanonical for transport to the remote
peer. At the remote peer, the address is either passed unchanged to Token
Ring-attached end systems or converted back to canonical if the destination
media is Ethernet. Note that when an SNA resource resides on Ethernet, if
you configure a destination SNA address in that device, you must use
canonical format. For example, Ethernet-attached 3174s must specify the MAC
address of the FEP in canonical format. If the Token Ring or noncanonical
format of the MAC address of the FEP is 4000.3745.0001, the canonical format
is 0200.ECA2.0080"
Well, after reading it the second time it looks like the person is talking
about "configuring the address on 3174". What about DLSW? If I were to put
icanreach statement on the local peer, or "dlsw mac" static pointer on the
remote-peer, I would use non-canonical address, correct?
