    iki tarafta da "encap ppp" denediniz mi?

    nasil bir trafikle test yapiyosunuz? sh ver koymamissiniz?

        Herkese selam

        Elimde 34.368 Mbps lik bir link var. Cisco 3640 router'ımda yüksek data rate için kullandığımız HSSI interface'i var. Karşı taraf HDLC encapsulation kullanıyor. Ben de interface'imde encapsulation'ı HDLC seçtigimde "Hssi0 is up, line protocol is up " oluyor. Ancak "show interface" dediğimde normalde 34 Mbps lik bir data akısı görmem gerekigi yerde 500Kbps lik bir data trafigi görebiliyorum. Gelen paketlerin çogunda CRC hatası var.
        Sizce sebep ne olabilir? Her halukarda line protocol up olduğunda data trafigini görmem gerekmiyor mu?
        Karşı taraftaki routerın Cisco değil Juniper oldugunu da belirteyim ancak Juniper routerda encapsulasyon Cisco-HDLC olarak konfigure edilmiş. Ayrıca trafik recieve-only.
        Yorumlarınızı bekliyorum.
