Ericsson SE-100 периодически теряет DHCP Один из двух Ericsson SE-100 не видит DHCP периодически

Используем в нашей сети два идентично настроены Ericsson SE-100. Далее первый SE-100(1) - IP-адрес 192.168.11.10, второй SE-100(2) - IP-адрес 192.168.11.12.

DHCP-сервер и оба SE-100 связываются между собой отдельным VLAN и кроме двух SE-100 DHCP-сервера в этом VLAN нет больше никого.

По SE-100(1) в логе наблюдаем большое количество сообщений:

 

May 21 17:10:23 172.17.0.10 May 28 17:10:23: [0002]: %DHCP-5-MRKG_SV_DEAD: Marking server: 192.168.11.1 in context: inet dead

May 21 17:10:23 172.17.0.10 May 28 17:10:23: [0002]: %DHCP-5-MRKG_SV_ALIVE: Marking server: 192.168.11.1 in context: inet alive

 

В логе SE-100(2) таких сообщений не наблюдается!

 

При этом по PING данный DHCP-сервер и SE-100(1) видят без потерь. Мониторинг выполнялся порядка одних суток, в результате 0% потерь.

 

По дампу проблем в работе SE100(1), которые могут влиять на взаимодействие SE100(1) и DHCP не

зафиксировано. Но, согласно логов чётко видно, что SE100(1) не получает часть служебных пакетов от DHCP

сервера из-за чего и помечает DHCP сервер как - Marking server: 192.168.11.1 in context: inet dead.
