3550-48的问题

6509下接的3550-48，光线千兆口做trunk,如何使得3550某端口上可同时使用两个vlan的地址？但不是所有的vlan的地址。

Command  Purpose  
Step 1
configure terminal
Enter global configuration mode.

Step 2
interface interface-id
Enter interface configuration mode and the port to be added to the VLAN.

Step 3
switchport trunk allowed vlan {add | except | none | remove} vlan-list
(Optional) Configure the list of VLANs allowed on the trunk.

For explanations about using the add, except, none, and remove keywords, refer to Catalyst 3550 Multilayer Switch Command Reference for this release.

The vlan-list parameter is either a single VLAN number from 1 to 1005 or a range of VLANs described by two VLAN numbers, the lesser one first, separated by a hyphen. Do not enter any spaces between comma-separated VLAN parameters or in hyphen-specified ranges.

All VLANs are allowed by default. You cannot remove any of the default VLANs from a trunk.

Step 4
end
Return to privileged EXEC.

Step 5
show interfaces interface-id switchport
Verify your entries in the Trunking VLANs Enabled field of the display.

Step 6
copy running-config startup-config
(Optional) Save your entries in the configuration file

3550下接了一台3com的1100，3550端口的配置是这样的：
swi trunk enc isl
swi mode trunk
swi trunk allowed add 1,21,28,31,1002-1005
这样的话，是不是3com下的机器可以配置成vlan21，28，31的地址都可以啊？

6509-〉3550-48下，接了3COM得1100，如何配置，使得1100下的机器可同时使用多个vlan得IP地址？6509上划分VLAN.

不明白楼主是什么意思，把随机文档贴出来是什么用意？如果你想同时使用两个vlan的地址，但不是所有的vlan的地址，你可以使用子端口啊
