Dell Switch N3048 設定筆記

這台設備也算是少碰了，有機會玩到就把他給記錄下來

1. Console 登入
2.建立admin使用者
3.建立vlan & 設定vlan ip
4.設定Telnet登入
5.設定OOB IP (管理Port)
6.設定Default Route
7.設定Port channel
8.設定802.1Q Trunk Port
9.設定Stacking
10.更新Firmware
11.設定存檔 & 恢復預設值 & 還原設定檔

1. Console 登入
Console Port |O|O|

2.建立admin使用者

console(config)#username admin password 123456 privilege 15 encrypted

3.建立vlan & 設定vlan ip

建立vlan 101

console(config)#vlan 101 

設定untaged port

console(config)#interface gigabitethernet 1/0/46 

console(config-if-Gi1/0/46)#switchport access vlan 101

設定 vlan interface ip

console(config)#interface vlan 101

console(config-if-vlan101)#ip address 192.168.101.1 255.255.255.0

4.設定Telnet登入

console(config)#line telnet

console(config-telnet)#login authentication default

5.設定OOB IP (管理Port)

console(config)#interface out-of-band

設定IP、MASK、Gateway

console(config-if)#ip address 10.192.1.85 255.255.255.0 10.192.1.126

查看OOB Port

console(config)#show interfaces status | include oob

6.設定Default Route

console(config)#ip route 0.0.0.0 0.0.0.0 192.168.1.1

查看路由表

console#show ip route

7.設定Port channel
選擇30-34 port

console(config)#interface range gigabitethernet 1/0/30-34

綁定為channel 10

console(config-if)#channel-group 10 mode active

查看Port channel

console#show interfaces port-channel 10

8.設定802.1Q Trunk Port

console(config)#interface gigabitethernet 1/0/30

console(config-if-Gi1/0/30)#switchport mode trunk

console(config-if-Gi1/0/30)#switchport trunk allowed vlan 1,10,20,30

查看Port 狀態

console#show interfaces port-channel 10

9.設定Stacking
需要相同Firmware 關機接上Stack cable 3台接線方式   Unit 1 接 Unit2 接Unit3 接Unit1

開機後只有Master Switch 可以透過Console & OOB 登入，而開機時預設是比較系統Mac address 來決定哪一台Switch為Master

console#show switch

    Management Standby   Preconfig    Plugged-in    Switch       Code
SW  Status     Status    Model ID     Model ID      Status       Version
--- ---------- --------- ------------- ------------- ------------- -----
1   Mgmt Sw              N3048         N3048         OK          6.2.1.6
2   Stack Mbr  Oper Stby N3048         N3048         OK          6.2.1.6

查看stack port狀態

console#show switch stack-ports

          Configured Running    Link         Link         Admin
Interface Stack Mode Stack Mode Status       Speed (Gb/s) Status
--------- ---------- ---------- ------------ ------------ ------------
Tw1/0/1   Stack      Stack      Link Up      21           Enabled
Tw1/0/2   Stack      Stack      Link Up      21           Enabled
Tw2/0/1   Stack      Stack      Link Up      21           Enabled
Tw2/0/2   Stack      Stack      Link Up      21           Enabled

強制設備Failover

console(config)#stack

console(config-stack)#initiate failover

Management unit will be reloaded.
           Are you sure you want to failover to the backup unit? (y/n) y

確認Master Switch是否已經轉換

console#show switch

    Management Standby   Preconfig     Plugged-in    Switch    Code
SW  Status     Status    Model ID      Model ID      Status    Version
--- ---------- --------- ------------- ------------- ------------- -----
1   Stack Mbr  Oper Stby N3048         N3048         OK          6.2.1.6
2   Mgmt Sw              N3048         N3048         OK          6.2.1.6

當有多台Switch stack 時，可以指定Failover 發生後指定Master Switch

console(config)#stack 

指定Unit 1 為Stanby

console(config-stack)#standby 1

console#show switch

    Management Standby   Preconfig     Plugged-in    Switch    Code
SW  Status     Status    Model ID      Model ID      Status    Version
--- ---------- --------- ------------- ------------- ------------- -----
1   Stack Mbr  Cfg Stby  N3048         N3048         OK          6.2.1.6
2   Mgmt Sw              N3048         N3048         OK          6.2.1.6

10.更新Firmware
Firmware 儲存有Active & Backup兩個位置
查看目前Firmware版本，開機會使用Active Firmware

console#show version

省略....
unit active      backup      current-active next-active
---- ----------- ----------- -------------- --------------
1    6.1.1.7     6.1.1.7     6.1.1.7        6.1.1.7

下載新版本Firmware (需登入)
http://www.dell.com/support/home/us/en/19/product-support/product/networking-n3000-series/drivers

下載完成後，需要建立TFTP Server or FTP or HTTP Server
複製

console#copy tftp://192.168.191.180/N3000_N2000v6.2.1.6.stk backup

Management access will be blocked for the duration of the transfer
Are you sure you want to start? (y/n) y

---- ----------- ----------- -------------- --------------
1    6.1.1.7     6.2.1.6     6.1.1.7        6.1.1.7

使用Backup Firmware後重開

console#boot system backup

console#reload

Management switch has unsaved changes.
Are you sure you want to continue? (y/n) y

Configuration Not Saved!

Are you sure you want to reload the stack? (y/n) y

console#show version

unit active      backup      current-active next-active
