主机
NetQ 代理监控 Linux 主机上的以下内容
- netlink
- 第 2 层：LLDP 和 VLAN 感知桥接
- 第 3 层：IPv4、IPv6
- 用于服务的 systemctl
在 Linux 主机上使用 NetQ 与在 Cumulus Linux 交换机上使用 NetQ 相同。例如，如果您想检查给定主机的 LLDP 邻居信息，请运行 netq show lldp 并指定主机名
cumulus@host:~$ netq server01 show lldp
Matching lldp records:
Hostname Interface Peer Hostname Peer Interface Last Changed
----------------- ------------------------- ----------------- ------------------------- -------------------------
server01 eth0 oob-mgmt-switch swp2 Mon Dec 2 21:22:55 2024
server01 eth1 leaf01 swp1 Mon Dec 2 21:22:55 2024
server01 eth2 leaf02 swp1 Mon Dec 2 21:22:55 2024
然后，要从交换机的角度查看 LLDP，请运行相同的命令，并指定交换机的主机名
cumulus@switch:~$ netq leaf01 show lldp
Matching lldp records:

要查看服务器的路由表，请运行 netq show ip routes
cumulus@host:~$ netq server01 show ip routes
Matching routes records:
