Asagidaki senaryoyu uygulayamiyorum cunku ben telekom a paketleri vlan interfaceleri olarak gonderiyorum. Mesela Ankara icin 444 vlan id tag ini kullanmam gerekiyor. Fastethernet interface I L2 calisiyor dolayisiyla interface yazdigin policy map leri Kabul etmiyor. Ornek vermem gerekirse

Gibi bir konfigurasyon yapiyorum.  

Benim yaptigim konfigurasyonda her paketi ayri ayri access-list ler ile yada nbar ile yakaliyorum classlar icerisinde tanimliyorum priority ve bandwidth degerlerini veriyorum. Bir policy icerisinde birden fazla lokasyon belirlemem mumkun degil benim konfigurasyonuma gore.. ayrica fa0/24 L2 oldugu icin service policy uygulayamiyorum.

once ana interface e bir policy uygulayip bu policy icinde her sehre gore class tanimlayip shaping uygulayabilirsin. Trafigi de access-listlere gore gerekli shaping gruplarina sokabilirsin, ornek asagida. karsi tarafta da bunun kucuk bir ornegini yapip sadece tek bir policy ve class ile shaping yapman lazim, yoksa telecom fazla gelen paketleri dusurur.

sorun olursa yolla tartisalim.
