Pozdrav. Imam čudan "problem" koji mi se javlja na 6509 šasiji. Naime HP blade mi je spojena na šasiju putem 16 linkova koji su s jedne strane spojeni na HP-ove switch-ove a s druge naravno na 6509. Prva nepoznanica. 1 Po1(SU) LACP Gi1/25(P) Gi1/33(P) Gi2/25(P) Gi2/33(P) Gi8/1(P) Gi8/9(D) Gi9/1(P) Gi9/9(P) 1 Po1B(SU) LACP Gi1/41(P) Gi2/41(P) Gi8/17(P) Gi8/25(P) Gi8/33(P) Gi9/17(P) Gi9/25(P) Gi9/33(P) Ja sam doživljavao portchannel tako da je 8 portova aktivno a 8 portova u "standbay-u". Ali kako ovdje piše to nije tako (zanemarite Gi8/9) ovdje su svi aktivni. Svi portovi su identično iskonfigurirani i svi su stavljeni u portchannel 1. Pitanje. Zašto se stvorio Po1B(SU)??? Druga nepoznanica. Ti portovi su u trunk-u. I propušteno je samo dva VLAN-a Dodavao sam treći VLAN (na interfaceu po1) i onda mi se u logu pojavile sljedeće stvari: Dec 24 11:38:24.125 CET: %EC-SP-5-CANNOT_BUNDLE_LACP: Gi1/41 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Dec 24 11:38:24.221 CET: %EC-SP-5-CANNOT_BUNDLE_LACP: Gi2/41 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Dec 24 11:38:25.493 CET: %EC-SP-5-CANNOT_BUNDLE_LACP: Gi8/17 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Dec 24 11:38:24.610 CET: %EC-SP-5-CANNOT_BUNDLE_LACP: Gi8/25 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Dec 24 11:38:25.213 CET: %EC-SPSTBY-5-CANNOT_BUNDLE_LACP: Gi1/41 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Dec 24 11:38:25.217 CET: %EC-SPSTBY-5-CANNOT_BUNDLE_LACP: Gi2/41 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Dec 24 11:38:25.225 CET: %EC-SPSTBY-5-CANNOT_BUNDLE_LACP: Gi8/17 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Dec 24 11:38:25.229 CET: %EC-SPSTBY-5-CANNOT_BUNDLE_LACP: Gi8/25 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Dec 24 11:38:24.682 CET: %EC-SP-5-CANNOT_BUNDLE_LACP: Gi8/33 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Dec 24 11:38:24.834 CET: %EC-SP-5-CANNOT_BUNDLE_LACP: Gi9/17 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Dec 24 11:38:25.233 CET: %EC-SPSTBY-5-CANNOT_BUNDLE_LACP: Gi8/33 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Dec 24 11:38:25.237 CET: %EC-SPSTBY-5-CANNOT_BUNDLE_LACP: Gi9/17 is not compatible with aggregators in channel 1 and cannot attach to them (vlan mask is different) Što je u jednu ruku i točno jer mi je od tog trećeg VLAN-a maska 27 a od ova prva dva 24. Onda ponovno vratim na početnu konfiguraciju i propustim samo dva VLAN-a koji su i bili iskonfigurirani ali stvar se ponovno pojavljuje u logu. Napomena. Jedan od ta dva VLAN-a koji su propušteni u portchannelu ima VLAN interface (layer3) dok drugi nema. Pa eto ako nekome nije teško da mi u kratkim crtama malo pojasni stvar bio bih iznimno zahvalan. |
