帮忙啊HELP~HELP~~~~~~
本帖最后由 lzpleehom 于 2009-8-10 19:24 编辑NP书上280说EHTHERCHANNEL~~ 有一条说一个ETHERCHANNEL内所有端口都要求具有相同VLAN开销配置。另外一条是即使接口配置了不同的STP端口路径开销，所有配置的兼容端口也可以形成ETHERCHANNEL。。。。我想问STP某个端口路径开销和端口的VLAN 开销有什么不一样啊，，谁能详细解答啊 诶,难得有人问这样的问题,哈哈~~`看看谁能答上来~~~哇哈哈哈~~~有意思 The EtherChannel VLAN cost feature provides load balancing of VLAN traffic across multiple channels that are configured with trunking.
You enter the set spantree channelvlancost command to set the initial spanning-tree costs for all VLANs in the channel. The set spantree channelvlancost command provides an alternate cost for some of the VLANs in the channel (assuming that you are trunking across the channel). This command allows you to have up to two different spanning-tree costs assigned per channel; some VLANs in the channel can have the "vlancost" while the remaining VLANs in the channel have the "cost."
The set spantree channelvlancost command creates a "set spantree portvlancost" entry to the configuration file for each port in the channel. After you enter the set spantree channelvlancost command, you must enter the set spantree portvlancost command for at least one port in the channel, specifying the VLAN or VLANs that you want associated with each port. This example shows what occurs when you enter each command:
Console> (enable) set spantree channelvlancost 856 10
Port(s) 3/47-48 vlan cost are **d to 16.
Channel 856 vlancost is set to 10.
look at here.~~~ zm 怎么没有哪个高手知道啊~ WHO CAN HELP ME 大哥答案就在这里
