1 VLANs and Robert Castellano 10/25/04 rc_vlan_01 Page 1

2 Introduction VLANs provide method for partitioning physical LAN networks into logical LAN segments. VLAN A A VLAN A VLAN B B VLAN B VLAN C C VLAN C VLAN Aware 10/25/04 rc_vlan_01 Page 2

3 802.1Q IEEE Std 802.1Q defines an architecture for Virtual d LANs, services provided in d LANs, and the protocols and algorithms involved in the provision of those services. 10/25/04 rc_vlan_01 Page 3

4 802.1Q VLAN Trunking 802.1Q specifies tagged frames for supporting VLAN trunking VLAN A VLAN Trunk VLAN A VLAN B Tagged Frames VLAN B VLAN Aware VLAN Aware Tagged frames relay VLAN associations across trunk ports 10/25/04 rc_vlan_01 Page 4

5 Bridging over Rings meets the 802.1D/802.1Q bridging requirements by treating the RPR as a shared LAN media d frames are flooded on RPR (i.e. non-local) Only non bridged frames may be directed (local-local) 10/25/04 rc_vlan_01 Page 5

6 802.1Q over Transforms the ring into a VLAN Trunk Port H 3 4 While not explicitely stated in standard, hosts sitting on an ring with 802.1Q tagged traffic should filter any tagged frames received for VLANs in which they are not a member. 10/25/04 rc_vlan_01 Page 6

7 802.1Q over Basic VLAN Rules 1 MAC G 6 2 MAC B MAC F 5 H 3 MAC C 4 MAC D MAC E In , any off ring stations which are members of the host RPR VLAN, must have unique MAC addresses as is required for normal LAN operation 10/25/04 rc_vlan_01 Page 7

8 802.1Q over Basic VLAN Rules 1 MAC B 6 2 MAC B MAC F 5 H 3 MAC C 4 MAC E In 802.1Q MAC end station addresses need not be unique. IVL and Mixed IVL/SVL properly resolves any MAC address conflicts. 10/25/04 rc_vlan_01 Page 8

9 Bridging and Intent of is to optimize RPR for bridged networks by sending directed frames in cases where possible rather than flooding. needs to be VLAN aware to ensure that traffic in different VLANs is properly delivered. The same MAC address may reside in different VLANs. Two stations with the same MAC address Two different paths to the same station. absolutely needs to distinguish between frames which are destined to different VLANs 10/25/04 rc_vlan_01 Page 9

10 Bridging and 1 MAC G If MAC G sends to MAC F, station 6 needs to determine based on the VID whether the frame should be forwarded through station 5 or station MAC B at station 2 needs to known when the frame is transmitted to local host at A (blue) and remote host A (red). 5 3 MAC F Two Paths to same ddress 4 MAC C Same ddress in different VLANs 10/25/04 rc_vlan_01 Page 10

11 Issue with and VLANs There is one scenario where transmission rules do not operate properly. A local host station on the RPR is a member of two different VLANs implementing IVL and communicates with an off ring host which happens to have the same MAC address as one of the local stations on the ring (but resides in a different VLAN). In this case, the off ring station with the duplicate MAC address in the other VLAN is not reachable. The MAC transmits using a directed transmission to the station in the incorrect VLAN violating the operation of the VLAN. The solution is for either the host to distinguish the VLAN and control the frame transmission, or restrict the host from communicating with duplicate MAC addresses. This problem can corrected by the by having the learn VLAN bindings from local host transmission. 10/25/04 rc_vlan_01 Page 11

12 Issue s in multiple VLANs 1 MAC B 6 2 MAC B MAC F 5 H 3 MAC C 4 MAC E If 4 sends a frame to MAC address A (in red VLAN), the RPR MAC will direct the frame to 1 (black). (red) will never receive the frame. 10/25/04 rc_vlan_01 Page 12

13 802.17B Solution 1 MAC B 6 2 MAC B 5 or Non- 3 MAC F 4 MAC C MAC E Allow to learn VLAN ID s with MAC addresses for local station addresses in SDB. In this case, if host 4 sends to (blue) the frame is directed to station 1. If host 4 sends to (red) the frame will either be directed through station 3 or flooded. In either case, (red) properly receives the frame. 10/25/04 rc_vlan_01 Page 13

14 TX for handling VIDs MAC Client Contains all local addresses and remote capable MAC addresses with VLAN associations SDB DA, Local Yes DA/VID in _DB? Yes Directed frame or Local-Local? No Flood frame MAC TX State Machine 10/25/04 rc_vlan_01 Page 14

15 Selective Update MAC Client SDB Selective update, Refresh, or purge Entry (Sstation, Estation, VID, local, ) Basic Frame (MACsa, MAC sa, VID) Extended Frame (MACsa, MAC saextended, VID) RPR MAC SDB updated with following : RPR station (Sstation), End Station (Estation), VID, (local) - if the frame came from a local RPR host () if the frame came from a capable station 10/25/04 rc_vlan_01 Page 15

16 Untagged or Priority Tagged Frames Frames which are untagged or priority tagged should be associated with the default VLAN. Default VLAN in the is configurable by LME. 10/25/04 rc_vlan_01 Page 16
