SPAN
I nwere ike iji ọrụ SPAN detuo ngwugwu site na ọdụ ụgbọ mmiri akọwapụtara gaa na ọdụ ụgbọ mmiri ọzọ dị na mgba ọkụ ahụ nke ejikọtara na ngwaọrụ nlekota netwọk maka nlekota na nchọpụta nsogbu netwọk.
SPAN anaghị emetụta mgbanwe ngwugwu n'etiti ọdụ isi mmalite na ọdụ isi mmalite. A na-edegharị ngwugwu niile na-abanye ma na-apụta site na ọdụ isi mmalite na ọdụ isi mmalite. Agbanyeghị, ọ bụrụ na okporo ụzọ enyo gafere bandwit nke ọdụ isi mmalite, dịka ọmụmaatụ, ọ bụrụ na ọdụ isi mmalite 100Mbps na-enyocha okporo ụzọ nke ọdụ isi mmalite 1000Mbps, enwere ike ịtụfu ngwugwu.
RSPAN
Ngosipụta ọdụ ụgbọ mmiri dịpụrụ adịpụ (RSPAN) bụ ndọtị nke ntụgharị ọdụ ụgbọ mmiri mpaghara (SPAN). Ngosipụta ọdụ ụgbọ mmiri dịpụrụ adịpụ na-emebi mmachi na ọdụ ụgbọ mmiri mmalite na ọdụ ụgbọ mmiri njedebe ga-adị n'otu ngwaọrụ ahụ, na-eme ka ọdụ ụgbọ mmiri mmalite na ọdụ ụgbọ mmiri njedebe gbasaa ọtụtụ ngwaọrụ netwọk. N'ụzọ dị otu a, onye nchịkwa netwọk nwere ike ịnọdụ ala n'ime ụlọ akụrụngwa etiti ma lelee ngwugwu data nke ọdụ ụgbọ mmiri enyo dịpụrụ adịpụ site na ihe nyocha.
RSPANNa-ebufe ngwugwu enyo niile na ọdụ ụgbọ mmiri nke ngwaọrụ Remote mirroring site na RSPAN VLAN pụrụ iche (a na-akpọ Remote VLAN). Ọrụ nke ngwaọrụ dị n'ụdị atọ:
1) Isi mmalite Mgbanwe: Ọdụ mgbanwe onyonyo dịpụrụ adịpụ, ọ bụ ya na-ahụ maka otu esi ebipụta ozi ọdụ mmiri sitere na isi mmalite mgbanwe, site na mbugharị VLAN dịpụrụ adịpụ, ziga ya n'etiti ma ọ bụ ịgbanwee.
2) Mgbanwe etiti: na netwọk dị n'etiti mgbanwe isi mmalite na ebe a na-aga, gbanwee, enyo site na nnyefe ngwugwu VLAN Remote gaa na nke ọzọ ma ọ bụ ịgbanwee n'etiti. Ọ bụrụ na njikọ isi mmalite na mgbanwe ebe a na-aga kpọmkwem, enweghị mgbanwe etiti dị.
3) Mgbanwe Ebe A Na-aga: Ọdụ ụgbọ mmiri ebe a na-aga enyo anya, enyo site na VLAN nke dị na Remote iji nata ozi site na ọdụ ụgbọ mmiri ebe a na-aga enyo iji lelee akụrụngwa.
ERSPAN
Encapsulated Remote port mirroring (ERSPAN) bụ ndọtị nke remote port mirroring (RSPAN). Na nnọkọ mirroring port remote port nkịtị, enwere ike izipu ngwugwu mirroring naanị na Layer 2 ma enweghị ike ịgafe na netwọk mirroring. Na nnọkọ mirroring port remote port mirroring, enwere ike ibufe ngwugwu mirroring n'etiti netwọk mirroring.
ERSPAN na-etinye ngwugwu enyo niile n'ime ngwugwu IP site na ọwara GRE ma na-ebuga ha na ọdụ ụgbọ mmiri ebe ngwaọrụ enyo dịpụrụ adịpụ na-aga. A na-ekewa ọrụ nke ngwaọrụ ọ bụla n'ime ụdị abụọ:
1) Isi mmalite Mgbanwe: encapsulation remote image source port of switch, bụ maka idetuo ozi isi mmalite site na mmepụta isi mmalite mgbanwe ọdụ ụgbọ mmiri mmepụta, site na GRE nke e tinyere n'ime nnyefe ngwugwu IP, mbufe mgbanwe gaa na nzube.
2) Mgbanwe Ebe: Ọdụ ụgbọ mmiri ebe mgba ọkụ na-aga, nke enyo anya na-aga, ga-enweta ozi ahụ site na ọdụ ụgbọ mmiri ebe mgba ọkụ na enyo enyo, mgbe e mechara nkewa, ozi GRE ezigara iji nyochaa akụrụngwa.
Iji mejuputa ọrụ enyo ọdụ ụgbọ mmiri dịpụrụ adịpụ, ngwugwu IP nke GRE tinyere ga-agarịrị na ngwaọrụ enyo ebe a na-aga na netwọkụ ahụ.

A na-akwado ya iji tinye ngwugwu ọ bụla akọwapụtara na okporo ụzọ ejidere na isi RSPAN ma ọ bụ ERSPAN wee wepụta ngwugwu ndị ahụ na sistemụ nlekota azụ ma ọ bụ mgba ọkụ netwọkụ
Nkwụsị Ngwugwu Ọwara
Akwadoro ọrụ mmechi ngwugwu ọwara ahụ, nke nwere ike ịhazi adreesị IP, ihe mkpuchi ihu, nzaghachi ARP, na nzaghachi ICMP maka ọdụ ụgbọ mmiri ntinye okporo ụzọ. A na-eziga okporo ụzọ a ga-anakọta na netwọk onye ọrụ ozugbo na ngwaọrụ ahụ site na usoro mkpuchi ọwara dịka GRE, GTP, na VXLAN
Mwepụ isi VxLAN, VLAN, GRE, MPLS
E tinyere isi VxLAN, VLAN, GRE, na MPLS n'ime ngwugwu data mbụ ma ziga mmepụta.
