Selamlar Yusuf

Maillere ancak bakabiliyorum :)

Sorunun ne oldugu cok acik aslinda:

 LMI enq sent 16487, LMI stat recvd 0,

16787 tane LMI gondermisiz, frame-relay switchden bir tane LMI stat paketi gelmemis.
Her 10 saniyede bir LMI paketi gonderdigimize gore, 16787x10=167870 saniye icinde tek bir paket almamisiz.
Bu tipik bir FR switch problemi...

Bu durumda PVC status tabiki DELETED olacaktir. Herhangi bir routera hicbir Fr baglantisi olmadan rastgele bir PVC tanimlayin ( 60 saniye bekleyin, en az bir tane full status report suresi gecsin) otomatik olarak DELETED gorunecektir.

Ya da LMI debuglarinda bir tane bile "Serial0(in): " paketi yok

ya da PVC ciktilarinda "input pkts 0 output pkts 73" , hic inout paketi yok

Romaya nerden gidersek gidelim, bu bir FR switch sorunudur :)

FR switch tarafinda teknik bir elemana bu maili forward et lutfen. Itirazi olursa da benim email adresimi verebilirsin:)

Kolay gelsin
