port channel , channel group

------------------
基本上只要這樣設定
config t
int g1/0/1
channel-group 1 mode active

int g1/0/2
channel-group 1 mode active

int port-channel 1
設定/功能如一般port



--------------------
L3 switch

config t
int g1/0/1
switch mode access
channel-group 2 mode active

int g1/0/2
switch mode access
channel-group 2 mode active
------
interface GigabitEthernet1/0/17,20
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,17
 switchport mode trunk
 channel-group 3 mode active

-----------------------

Switch(config-if)#channel-group 1 mode ?

  active         Enable LACP unconditionally
  auto           Enable PAgP only if a PAgP device is detected
  desirable    Enable PAgP unconditionally
  on              Enable Etherchannel only
  passive      Enable LACP only if a LACP device is detected
-----------------------

switch(config)# lacp system-priority 32768

n5k ios upgrade 升級

正常是要看cisco的 n5k_upgrade_downgrade_503這份文件,有完整說明和注意事項,

如果懶的看,或是看不懂,或是google也找不到簡單明瞭的方式,就看看下面簡潔說明

#前置動作&安全規定

1.switch# show configuration session summary

   確認沒使用者連線進行設定

2.此動作可能會導致 topology 變動,應先避免
   (STP or FC fabric changes that affect zoning)

3.應確定網路的穩定性,和避免電力中斷的可能

4.至少200MB的空間,足以上傳新的ios

以上

----------------------------------------------

好的,以上都ok後,那就來更新ios吧,找個 utp port 來上傳ios吧

.

.

.

.

.

.

只有mgmt0可以插,沒得選所以就把網路線插近這個port......

1.設定 mgmt0 ip

    int mgmt0   ( ex: 192.168.1.1/24 )

    *自己電腦tftp server ip(192.168.1.2/24)

    互聘(ping)

    *在n5k上輸入: ping 192.168.1.2 vrf management 才可以聘
     (透過mgmt0)

2.上傳ios到 bootflash:

應該知道有(吧?!)有kickstart 和 system(ios) 這兩種東西,需具備這兩樣才能完整更新n5k ios
N5K-1# copy tftp://192.168.1.2/n5000-uk9-kickstart.4.2.1.N2.1.bin bootflash:
Enter vrf (If no input, current vrf 'default' is considered): management

把這2個上傳到bootflash:後

先驗證ios:  show install all impact kickstart <image> system<image> 

switch# show install all impact kickstart bootflash:n5000-uk9-kickstart.4.2.1.N1.1a.bin system bootflash:n5000-uk9.4.2.1.N1.1a.bin 

都跑到100% success 就沒事,進行下一動.

3. 安裝ios install all kickstart <image> system<image> 

switch# install all kickstart bootflash:n5000-uk9-kickstart.4.2.1.N1.1.bin system bootflash:n5000-uk9.4.2.1.N1.1.bin

*但是我這樣輸入也是可以?!

switch# install all kickstart n5000-uk9-kickstart.5.2.1.N1.5.bin system n5000

 uk9.5.2.1.N1.5.bin 

讓他跑跑跑...會出現下面這選項,預設是N,但是要輸入Y,然後確定.

Switch will be reloaded for disruptive upgrade.

Do you want to continue with the installation (y/n)?  [n] Y

然後繼續跑跑跑,跑完後重開機.

show version 看版本正確否, 收工!
