Roseli, For sure, native vlans need to match , no matter SW revision, product, vendor , whatever . If not , imagine vlan 2 native in side A and 3 in side B . SIde A won't tag vlan 2 frames, and side B won't tag vlan 3 frames .
Trunk will come up, but both vlans won't work properly . Regarding the other question , as far as I know, set trunk desirable works only between two switches in same VTP domain. set trunk on should always works , not sure about negotiate and nonegotiate . > _____________________________________ > Henrique Issamu Terada, CCIE # 7460 > IT Support - Open Network > CPM S.A. - Tecnologia criando valor > Tel.: 55 11 4196-0710 > Fax: 55 11 4196-0900 > [EMAIL PROTECTED] > www.cpm.com.br > -------------------------------------------------------------------------- > ------------------- > Esta mensagem pode conter informagco confidencial e/ou privilegiada.
