使用不能 Vlan まとめ
各メーカーのネットワーク機器で、制限あり or 使用不能な Vlan ID についてまとめました。
Cisco
Router / Catalyst 共通
1002-1005 : Token Ring and FDDI VLANs [1]
1006-4094 : VTP トランスペアレントモードが必要 [2]
Catalyst 3850XS / 9400 / 9500 / 9600 StackWise Virtual
4094 : StackWise Virtual [3]
Nexus 9000
3968-4095 : Internally allocated [4]
Juniper
EX8200 バーチャル シャーシ
4093-4094 : Virtual Chassis [5]
QFX3500 / QFX5100
4093 : Reserved [5]
Arista
EOS [6]
Routed Port も Vlan ID を内部で消費する
内部で消費する Vlan ID は、未設定の場合 1006-4094 から自動でアサインされる
vlan internal order ascending / descending で昇順・降順を制御可能
vlan internal order descending range 4000 4094 のように予めアサインも可能

- ↑ Restrictions for Cisco StackWise Virtualhttps://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9500/software/release/17-3/configuration_guide/ha/b_173_ha_9500_cg/configuring_cisco_stackwise_virtual.html#reference_kph_hgh_nlb When deploying Cisco StackWise Virtual, ensure that VLAN ID 4094 is not used anywhere on the network. All inter-chassis system control communication between stack members is carried over the reserved VLAN ID 4094 from the global range.

By default, the switch allocates VLANs in ascending order. The default allocation range is between VLAN 1006 and VLAN 4094.
