Symptom

Filing this bug to document the behavior since sent traffic does not include the VLAN Tag - unlike received traffic. 1. Example: ARP in non-native VLAN received by CPU includes the VLAN Tag Ethernet II, Src: 00:50:56:62:6b:1c (00:50:56:62:6b:1c), Dst: ff:ff:ff:ff:ff:ff (ff:ff:ff:ff:ff:ff) Destination: ff:ff:ff:ff:ff:ff (ff:ff:ff:ff:ff:ff) Address: ff:ff:ff:ff:ff:ff (ff:ff:ff:ff:ff:ff) .... ...1 .... .... .... .... = IG bit: Group address (multicast/broadcast) .... ..1. .... .... .... .... = LG bit: Locally administered address (this is NOT the factory default) Source: 00:50:56:62:6b:1c (00:50:56:62:6b:1c) Address: 00:50:56:62:6b:1c (00:50:56:62:6b:1c) .... ...0 .... .... .... .... = IG bit: Individual address (unicast) .... ..0. .... .... .... .... = LG bit: Globally unique address (factory default) Type: 802.1Q Virtual LAN (0x8100) 802.1Q Virtual LAN, PRI: 0, CFI: 0, ID: 701 000. .... .... .... = Priority: 0 ...0 .... .... .... = CFI: 0 .... 0010 1011 1101 = ID: 701 Type: ARP (0x0806) Trailer: 000000000000000000000000000000000000 Address Resolution Protocol (request) Hardware type: Ethernet (0x0001) Protocol type: IP (0x0800) Hardware size: 6 Protocol size: 4 Opcode: request (0x0001) [Is gratuitous: False] Sender MAC address: 00:50:56:62:6b:1c (00:50:56:62:6b:1c) Sender IP address: 10.102.63.201 (10.102.63.201) Target MAC address: 00:00:00:00:00:00 (00:00:00:00:00:00) Target IP address: 10.102.63.193 (10.102.63.193) 2. Example: ARP reply sent by CPU does not include the VLAN Tag ("expected behavior"). Tag is added later.
