💖 DESCRIPTION 💖

ip ntable controls the parameters for the neighbour tables. no cap. it's the main character of this whole page. 👑

🦋 ip ntable show — list the ip neighbour tables 🦋

This command displays neighbour table parameters and statistics. it's giving ✨receipts✨, bestie.

  • dev DEV — only list the table attached to this device. just the one. one device only. 💅
  • name NAME — only lists the table with the given name. yes, specifically that name, not a vibe-adjacent one. 🙈

🎀 ip ntable change — modify table parameter 🎀

This command allows modifying table parameters such as timers and queue lengths. it's the makeover episode of the neighbour table. 💄

  • name NAME — the name of the table to modify. you gotta name it before you change it, periodt.
  • dev DEV — the name of the device to modify the table values. which device are we changing? say it. 📢

🌈 EXAMPLES 🌈

okay here's the part you actually came for. 🍓

ip ntable show dev eth0

Shows the neighbour table (IPv4 ARP and IPv6 ndisc) parameters on device eth0. both of them. ARP and ndisc. multi-tasking queen. 👑

ip ntable change name arp_cache queue 8 dev eth0

Changes the number of packets queued while address is being resolved from the default value (3) to 8 packets. glow up from 3 to 8, we love to see it. 🔥
