Você pode experimentar /sbin/ifconfig -a ou ip link show e mais ethtool .
O último mostra estados de conexão.
Eu preciso descobrir quantas portas físicas totais meu servidor possui e quantas estão em uso e quantas são gratuitas. Você pode ajudar gentilmente a encontrar:
Isto é o que eu encontro na saída dmidecode:
# dmidecode | egrep -i "PCI|Available|in use"

Como eu concluo que quantas portas físicas estão em uso e quantas estão disponíveis? gentilmente ajuda
Você pode experimentar /sbin/ifconfig -a ou ip link show e mais ethtool .
O último mostra estados de conexão.
Aqui está o que você precisa fazer.
Primeiro, localize todas as portas NIC, cada linha é uma porta.
-bash-4.1# lspci | grep -i ethernet
03:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
03:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
04:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
04:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
08:00.0 Ethernet controller: Solarflare Communications SFC9120 (rev 01)
08:00.1 Ethernet controller: Solarflare Communications SFC9120 (rev 01)
0b:00.0 Ethernet controller: Solarflare Communications SFC9020 [Solarstorm]
0b:00.1 Ethernet controller: Solarflare Communications SFC9020 [Solarstorm]
0e:00.0 Ethernet controller: Intel Corporation 82580 Gigabit Network Connection (rev 01)
0e:00.1 Ethernet controller: Intel Corporation 82580 Gigabit Network Connection (rev 01)
0e:00.2 Ethernet controller: Intel Corporation 82580 Gigabit Network Connection (rev 01)
0e:00.3 Ethernet controller: Intel Corporation 82580 Gigabit Network Connection (rev 01)
11:00.0 Ethernet controller: Solarflare Communications SFC9120 (rev 01)
11:00.1 Ethernet controller: Solarflare Communications SFC9120 (rev 01)
Como sei qual porta é qual interface NIC? (exemplo, eth0)
-bash-4.1# ethtool -i eth0
driver: sfc
version: 4.1.2.1003b
firmware-version: 4.2.2.1003 rx1 tx1
bus-info: 0000:08:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no
Agora você pode ver o bus-info: 0000:08:00.0 corresponde a 08:00.0 Ethernet controller: Solarflare Communications SFC9120 (rev 01)
Portanto, eth0 é uma das portas do Solarflare e é fácil verificar se ela está ativa
ip link show eth0
Agora você poderá descobrir quantas portas NIC você tem, quantas portas livres em cada cartão.
Obrigado

Para relacionar um cartão / porta a um nome de interface específico, os seguintes comandos também podem ser úteis.
O link na / sys / class / net tem o número do barramento que pode mapear uma porta para um nome de interface.
