Ø whakawhāitihia te maha o te tauranga hononga morahi i waenga i te kaihautu me te atanga Itarangi mo te maha o nga here, te whakanui i te bandwidth me te taapiri o te punaha.
Ø ACL kaha, tautoko L2 – L4 paparanga raraunga tātariØ
Te rarangi whakahaere kaupapa here, te whakahaere rere
8.Easy ki te whakamahi me te pupuri
Ka taea te whakahaere ma te Tukutuku, SNMP me etahi atu
Ø tautoko te kawa XModem, ka taea ma te TFTP/ZMODEM whakamohoatanga rorohiko me te BootRom
Ø tautoko SFP +, me te hototahi whakamuri XFP, etc
9. He kaha te whakahaere waka me te whakahaere haapurororaa
Te kitenga aunoa me te aukati i te tupuhi haapurororaa, tautoko i te kitenga karere a IGMP, me te whakaiti i te waipuke o te panui panui.
Ø e tautoko ana i te aratau matarua-katoa me te aratau haurua-rua o te mana rere
Ø tautoko atanga Itarangi i roto i te 1 m rite te reiti whakawhāiti te roa taahiraa
