chert Posted June 3, 2010 (edited) · Report post Да. пользуйте tcpdump -p Edited June 3, 2010 by chert Share this post Link to post Share on other sites
pfduch Posted June 3, 2010 · Report post С -p работать будет иначе в обоих случаях, но не поможет. tcpdump на parent interface всегда "видит" пакеты в VLAN'ах на нём. Используйте выражение not vlan Share this post Link to post Share on other sites
