am sters ce nu era interesant. Ce e interesant e dece ai de 3.26x mai multe pachete filtered decit received. Incearca sa pui in portul ala ceva computer/laptop care nu filtreaza pachetele ca sa vezi cu un tcpdump ce trafic e acolo. Filtrul ala din un google rapid e in NIC deci pachetele filtrate nu ajung la linux. Poate ai gramada de pachete non IP/ARP care switch-ul le arunca pe toate interfetele din ceva motiv dar e interesant de vazut ce trafic e ala. > > > > ethtook -k eth0 # status offloading > > > # ethtool -k eth0 > Offload parameters for eth0: > Cannot get device udp large send offload settings: Operation not supported > rx-checksumming: on > tx-checksumming: on > scatter-gather: on > tcp segmentation offload: on > udp fragmentation offload: off > generic segmentation offload: off > generic-receive-offload: off > > > > ethtook -a eth0 # status pause > > > ethtool -a eth0 > Pause parameters for eth0: > Autonegotiate: on > RX: on > TX: on > > > > > > poti obtine informatii similare din celalalt capat (switch) ? adica daca > ai > > linuxul X legat in portul Y in switch, output-ul comenzilor pe linux + > > informatiile similare de pe portul corespondent din switch ajuta. > > > > show interfaces ethernet 11/23 > GigabitEthernet11/23 is up, line protocol is up > Hardware is GigabitEthernet, address is 0012.f23f.3b00 (bia > 0012.f23f.3b00) > Configured speed auto, actual 1Gbit, configured duplex fdx, actual fdx > Configured mdi mode AUTO, actual MDIX > Member of L2 VLAN ID 102, port is untagged, port state is Forwarding > STP configured to ON, Priority is level0, flow control enabled > Force-DSCP disabled > mirror disabled, monitor disabled > Not member of any active trunks > Not member of any configured trunks > No port name > MTU 1518 bytes, encapsulation ethernet > 300 second input rate: 579553 bits/sec, 291 packets/sec, 0.06% utilization > 300 second output rate: 93822066 bits/sec, 24187 packets/sec, 9.61% > utilization > 352571352 packets input, 92636820039 bytes, 0 no buffer > Received 54059 broadcasts, 0 multicasts, 352517293 unicasts > 0 input errors, 0 CRC, 0 frame, 0 ignored > 0 runts, 0 giants, DMA received 352571352 packets > 43102015231 packets output, 37874584621589 bytes, 0 underruns > Transmitted 123807465 broadcasts, 15879877 multicasts, 42962327889 > unicasts > 0 output errors, 0 collisions, DMA transmitted 43102015231 packets > > >> 89mbits/sec output rate pe interfata direct conectata, pe cand iptraf > arata 100kbits/sec > > > > > > Spor. > > > > > > > > > > Va multumesc si va doresc Sarbatori Fericite. > > > > > > ---------------- > > > Bogdan > > > > > _______________________________________________ > > RLUG mailing list > > [email protected] > > http://lists.lug.ro/mailman/listinfo/rlug > > > _______________________________________________ > RLUG mailing list > [email protected] > http://lists.lug.ro/mailman/listinfo/rlug > _______________________________________________ RLUG mailing list [email protected] http://lists.lug.ro/mailman/listinfo/rlug
