Cisco разное (ааа, logs, cli, etc)

  • Настройка native vlan на роутере Cisco
В топологии Router-on-a-Stick мы можем настроить Native vlan на sub-интерфейсе:
Router(config-if)#interface GigabitEthernet 0/0.12 Router(config-subif)#encapsulation dot1Q 12 native
  • Сбор объемного вывода.
# Cisco Catalyst 2960 example
show running-config | redirect flash:test.cfg
more test.cfg
  • Удобно, когда кто-то наплодил VLAN.
    csco(config)#no vlan 10-100
  • Настройка привилегий только на shutdown/ip address для определенного уровня (например, для тех. поддержки):
privilege interface level 5 shutdown
privilege interface level 5 description
privilege interface level 5 ip address
privilege configure level 5 interface
privilege exec level 5 configure terminal
  • .Jun 1 19:20:18.721: %C4K_HWPORTMAN-4-BLOCKEDTXQUEUE: Blocked transmit queue HwTxQId7 on Switch Phyport Gi2/17, count=39390
    Recommended Action: Configure both sides of the link to autonegotiate for speed and duplex. Check if pause is in effect, resulting in the queue being blocked, Issue the shut/no shut command to recover the port. If the problem persists, move the connected device to another port and see if the problem happens there. If neither of these solves the problem, issue the hw-module reset command in order to reboot the switch and reset the line card.
