Linuxで合計NICカードと使用可能な物理ポートの合計を確認する方法
サーバーにある物理ポートの総数、使用中のポートの数、空きポートの数を確認する必要があります。あなたは親切にそれを見つける方法を手伝ってくれますか：
これは私がdmidecode出力から見つけたものです：
# dmidecode | egrep -i "PCI|Available|in use"
PCI is supported
ESCD support is available
Designation: PCI-E Slot 1

# dmidecode | grep -i "NIC"
HP BIOS NIC PCI and MAC Information
NIC 1: PCI device 04:00.0, MAC address 00:1E:0B:C0:F4:92
NIC 2: PCI device 42:00.0, MAC address 00:1E:0B:C0:F4:90
HP BIOS iSCSI NIC PCI and MAC Information
NIC 1: PCI device 04:00.0, MAC address 00:1E:0B:C0:F4:93
NIC 2: PCI device 42:00.0, MAC address 00:1E:0B:C0:F4:91
[root@eir1 network-scripts]# cat ifcfg-eth[0123] | grep -i HWADDR
HWADDR=00:1E:0B:C0:F4:92
HWADDR=00:1E:0B:C0:F4:90
HWADDR=00:26:55:e6:75:5c
HWADDR=00:26:55:e6:75:5d
これから、使用中の物理ポートの数と使用可能なポートの数をどのように結論付けることができますか？親切に助けて
これがあなたがする必要があることです。
最初にすべてのNICポートをリストします。各行は、ポートです。
_-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)
_どのポートがどのNICインターフェイスか）を知るにはどうすればよいですか？（例、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
_これで、_bus-info: 0000:08:00.0_が08:00.0 Ethernet controller: Solarflare Communications SFC9120 (rev 01)と一致することがわかります。
ドライバー名も簡単にわかります。この場合、sfcは「SolarflareCommunications」を示します。
したがって、_eth0_はSolarflareポートの1つであり、稼働しているかどうかを簡単に確認できます。
_ip link show eth0_
これで、NICポートの数、各カードの空きポートの数を確認できます。
ありがとう

他に何か要りますか？関連するすべてのコードを見つけることができます dmidecodeのsourceforgeページで
/sbin/ifconfig -aまたはip link show、さらにethtoolを試すことができます。
後者は接続状態を示しています。
カード/ポートを特定のインターフェイス名に関連付けるには、次のコマンドも便利です。
/ sys/class/netのリンクには、ポートをインターフェイス名にマップできるバス番号があります。
