适用场景

  • ONTAP 9
  • LLDP 多播

问题描述

  • 在非 CNA 端口的 LLDP 多播期间, ONTAP 会将 e0M 端口的 MAC 地址作为非 CNA 端口的机箱 ID 公布。
用于非 CNA 端口 
在交换机端:  
# show lldp neighbors
Neighbor Neighbor Neighbor
Port Chassis ID    Port ID TTL Age System Name
===============================================================================
10 D0:39:EA:XX:YY:ZZ e0e     121 5    node3a
11 D0:39:EA:XX:YY:ZZ e0f     121 5   node3a
 
::> node run -node node3a ifconfig e0M
e0M: flags=8843<up,broadcast,running,simplex,multicast> metric 0 mtu 1500
options=6c03bb<rxcsum,txcsum,vlan_mtu,vlan_hwtagging,jumbo_mtu,vlan_hwcsum,tso4,tso6,vlan_hwtso,linkstate,rxcsum_ipv6,txcsum_ipv6>
ether D0:39:EA:XX:YY:ZZ
hwaddr D0:39:EA:XX:YY:ZZ
inet xx.yy.61.zz netmask 0xffffff00 broadcast xx.yy.61.255 Services: 0x00030408 Vserver ID: -1
media: Ethernet autoselect (1000baseT)
 
注意:e0e 和 e0f 是非 CNA 端口,属于 10G/25G 以太网控制器 CX5-Mezz
