O lenei mataupu o loʻo tuʻuina atu se faʻamatalagaview o le fou ma suia uiga lelei o Auaunaga (QoS) i le Modular QoS Configuration Taiala mo Cisco 8000 Series Routers.

Vaega 2: Fa'atonuina o Ta'avale Ta'avaleview
O lenei mataupu o loʻo faʻamatalaina ai le lautele o le pulega o fefaʻatauaiga, e aofia ai le faʻatautaia masani o fefaʻatauaiga, pulega o feoaiga i luga o lau alalaupapa, tapulaʻa o le VoQ faʻataʻitaʻiga, tofi faʻavae QoS, ma le faʻaogaina o le Cisco Modular QoS CLI e faʻaogaina ai le QoS.

Aotelega
O le lautele o le pulega o feoaiga e aofia ai le puleaina ma le faʻamuamua o fefaʻatauaiga o fesoʻotaʻiga ina ia mautinoa lelei ma faʻatuatuaina faʻamatalaga faʻamatalaga.

Fa'aleaganu'u Pulega Ta'avale
Fa'aleaganu'u fa'atonuga o feoaiga e aofia ai le fa'atinoina o auala eseese e fa'atautaia ai fefa'ataua'iga o feso'ota'iga, e pei o le fa'atulagaina o ta'avale, leoleo, ma le tu'i.

Puleaina o Ta'avale i luga o lau Router
O lenei vaega o loʻo faʻamatalaina pe faʻapefea ona faʻatinoina le pulega o fefaʻatauaiga i Cisco 8000 Series Routers, e aofia ai le faʻaogaina o le Modular QoS CLI (MQC) e faʻamalamalamaina ma faʻaoga faiga faʻavae QoS.

Tapula'a o le VoQ Model
O le Voice over Quantum (VoQ) faʻataʻitaʻiga e iai ni tapulaʻa i tulaga o le faʻalauteleina ma le lavelave. O lenei vaega o loʻo faʻatalanoaina nei tapulaʻa ma tuʻuina atu faʻamatalaga i le puleaina o QoS i ia faʻaaliga.

Faiga Fa'avae QoS

O tofi fa'avae QoS e fa'atatau i le agava'a e maua ai fa'atonuga QoS mai faiga fa'avae matua. O lenei vaega o loʻo faʻamatalaina le manatu o le QoS faiga faʻavae tofi ma ona faʻamanuiaga.

Cisco Modular QoS CLI e faʻapipiʻi QoS
O le Cisco Modular QoS CLI (MQC) o se faʻatonuga laina faʻaoga e faʻaogaina ma faʻaogaina faiga faʻavae QoS i Cisco 8000 Series Routers. O lenei vaega e maua ai fa'amatalaga taua e uiga i le fa'aogaina o le MQC mo le fa'atinoina o le QoS.

Vaega 3: Manatu Taua e uiga i Faiga Faʻavae Tuila a le MQC
O lenei mataupu o loʻo faʻamamafaina ai manatu taua ma mea e tatau ona matauina pe a faʻatulagaina le faiga faʻavae a le MQC egress queuing mo le faʻatinoga lelei o le QoS.

Fesili e Fai soo (FAQ)

Q: O le a le pulega o feoaiga?
A: O le fa'afoega o ta'avale e aofia ai le fa'atonuina ma le fa'amuamua o felauaiga o feso'ota'iga ina ia mautinoa lelei ma fa'atuatuaina felauaiga fa'amatalaga.

Q: E faʻafefea ona ou faʻatulagaina faiga faʻavae QoS ile Cisco 8000 Series Auala?
A: E mafai ona e faʻaogaina le Cisco Modular QoS CLI (MQC) e faʻapipiʻi ma faʻapipiʻi faiga faʻavae QoS i Cisco 8000 Series Routers.

Q: O a tapulaa o le VoQ faʻataʻitaʻiga?
A: O le VoQ faʻataʻitaʻiga e iai tapulaʻa i tulaga o le faʻalauteleina ma le lavelave. E taua le malamalama i nei tapulaʻa pe a pulea le QoS i VoQ-faʻavae fesoʻotaʻiga.
