• Cấu hình VTP mặc định

• Cấu hình VTP
Phần sau trình bày các vấn đề cần thiết khi cấu hình VTP:

 Cấu hình VTP Server
 Cấu hình VTP Client
 Disabling VTP (VTP Transparent Mode)
 Enabling VTP Version 2
 Disabling VTP Version 2
 Cấu hình VTP Pruning
 Disabling VTP Pruning
 Monitoring VTP

 Cấu hình VTP Server

Ví dụ:

Console> (enable) set vtp domain Lab_Network
VTP domain Lab_Network modified
Console> (enable) set vtp mode server
VTP domain Lab_Network modified
Console> (enable) show vtp domain

Domain Name Domain Index VTP Version Local Mode Password
-------------------------------- ------------ ----------- ----------- ----------
Lab_Network 1 2 server -

Vlan-count Max-vlan-storage Config Revision Notifications
---------- ---------------- --------------- -------------
10 1023 40 enabled

Last Updater V2 Mode Pruning PruneEligible on Vlans
--------------- -------- -------- -------------------------
172.20.52.70 disabled disabled 2-1000
Console> (enable)

 Cấu hình VTP Client

Ví dụ:

Console> (enable) set vtp domain Lab_Network
VTP domain Lab_Network modified
Console> (enable) set vtp mode client
VTP domain Lab_Network modified
Console> (enable) show vtp domain
Domain Name Domain Index VTP Version Local Mode Password
-------------------------------- ------------ ----------- ----------- ----------
Lab_Network 1 2 client -

Vlan-count Max-vlan-storage Config Revision Notifications
---------- ---------------- --------------- -------------
10 1023 40 enabled

Last Updater V2 Mode Pruning PruneEligible on Vlans
--------------- -------- ------- -------------------------
172.20.52.70 disabled disabled 2-1000
Console> (enable)

 Tắt chế độ VTP (VTP Transparent Mode)

Ví dụ:

Console> (enable) set vtp mode transparent
VTP domain Lab_Net modified
Console> (enable) show vtp domain
Domain Name Domain Index VTP Version Local Mode Password
-------------------------------- ------------ ----------- ----------- ----------
Lab_Net 1 2 Transparent -

Vlan-count Max-vlan-storage Config Revision Notifications
---------- ---------------- --------------- -------------
10 1023 0 enabled
Last Updater V2 Mode Pruning PruneEligible on Vlans
--------------- -------- -------- -------------------------
172.20.52.70 disabled disabled 2-1000
Console> (enable)

 Cho phép VTP Version 2

Ghi chú: VTP version 1 và VTP version 2 không thể kết hợp trong cùng VTP domain. Các switch trong cùng VTP domain phải sử dụng cùng VTP version. Chỉ cho phép VTP version 2 nếu tất cả switch trong VTP domain đều hỗ trợ VTP version 2.

Ví dụ:

Console> (enable) set vtp v2 enable
This command will enable the version 2 function in the entire management domain.
All devices in the management domain should be version2-capable before enabling.
Do you want to continue (y/n) [n]? y
VTP domain Lab_Net modified
Console> (enable) show vtp domain
Domain Name Domain Index VTP Version Local Mode Password
-------------------------------- ------------ ----------- ----------- ----------
Lab_Net 1 2 server -

Vlan-count Max-vlan-storage Config Revision Notifications
---------- ---------------- --------------- -------------
10 1023 1 enabled

Last Updater V2 Mode Pruning PruneEligible on Vlans
--------------- -------- -------- -------------------------
172.20.52.70 enabled disabled 2-1000
Console> (enable)

 Tắt VTP Version 2

Ví dụ:

Console> (enable) set vtp v2 disable
This command will disable the version 2 function in the entire management domain.
Warning: trbrf & trcrf vlans will not work properly in this mode.
Do you want to continue (y/n) [n]? y
VTP domain Lab_Net modified
Console> (enable)

 Cấu hình VTP Pruning

Ví dụ sau cho thấy cách bật chế độ VTP pruning trên VTP domain, và khiến các VLAN 2-99, 250-255, and 501-1000 cho phép pruning:

Console> (enable) set vtp pruning enable
This command will enable the pruning function in the entire management domain.
All devices in the management domain should be pruning-capable before enabling.
Do you want to continue (y/n) [n]? y
VTP domain Lab_Network modified
Console> (enable) clear vtp pruneeligible 100-500
Vlans 1,100-500,1001-1005 will not be pruned on this device.
VTP domain Lab_Network modified.
Console> (enable) set vtp pruneeligible 250-255
Vlans 2-99,250-255,501-1000 eligible for pruning on this device.
VTP domain Lab_Network modified.
Console> (enable) show vtp domain
Domain Name Domain Index VTP Version Local Mode Password
-------------------------------- ------------ ---------- ----------- ----------
Lab_Network 1 2 server -

 Tắt chế độ VTP Pruning

Ví dụ:

Console> (enable) set vtp pruning disable
This command will disable the pruning function in the entire management domain.
Do you want to continue (y/n) [n]? y
VTP domain Lab_Network modified
Console> (enable)

 Monitoring VTP

Ví dụ:

Console> (enable) show vtp statistics
VTP statistics:
summary advts received 4690
subset advts received 7
request advts received 0
summary advts transmitted 4397
subset advts transmitted 8
request advts transmitted 0
No of config revision errors 0
No of config digest errors 0
VTP pruning statistics:
