As anEthernet MAC address appears in the reverse bit order of a Token-Ring MACaddress, bit order reversal is required in MAC address configuration (for example, aMAC address 0028-3300-2af5 appears to be 0014-cc00-54af after bit orderreversal). If the peer end is Token-Ring, bit order reversal is not required.Configuring DLSw withVLAN SupportNetwork requirementsAs shown in Figure 39, Ethernet 1/1 of the Ethernet switch is connected with anIBM host, Ethernet 1/0 of the switch is connected with Router A, and Ethernet 1/1of Router B is connected with an SNA host. Perform the following configuration sothat the IBM host can communication with the SNA host over the Internet:■ Add Ethernet 1/1 to VLAN 2, and configure Ethernet 1/0 as a trunk port,allowing VLAN 2 of Ethernet 1/1 to pass.■ Configure a sub-interface Ethernet 1/1.1 on Ethernet 1/1 of Router A and addthis sub-interface to VLAN 2.Configure DLSw on Router A and Router B.
