最近還碰到一個現(xiàn)象，一個網(wǎng)絡(luò)中VTP Server 是6509，下面的VTP Client交換機有35xx和2924，由于29xx最大同時只能支持64個VLAN，所以當6509上定義的VLAN超過了64個之后，與6509直接相連的2924不能學(xué)習到新加的VLAN，但原有VLAN工作正常；而經(jīng)過35xx連接6509的2924交換機則出現(xiàn)了自動從VTP Client模式轉(zhuǎn)成Transparent模式的現(xiàn)象，除VLAN1之外不通，需要重新啟動才能正常工作。假如這些2924交換機上的端口需要加入新增的VLAN，則需要手工修改其上的VLAN定義，刪去一些舊的VLAN，增加新的VLAN。
