Добрый день.
Есть проблема, есть связка Cisco Catalyst 2960s и модуля NM-16ESW установленного в Cisco 2610.
Связаны транковым портом. Все работает, кроме как не передается vlan 1.
2 дня бьюсь, причина скорее всего перед глазами но не вижу.Куски конфига на транковых портах:

Все виланы проходят, кроме первого.
Оставить его по-умолчанию нельзя - оператор не пропускает.
Какие мысли?
