Cisco SG500X Channel-port has no performance

Hi!

I'm linking two Cisco switch SG500X and do not want them in stacking , then set up the two switch one chanel -group with four ports for me to ensure high throughput between two devices .

I'm transferring files from a PC connected to the first switch and another PC connected to the second switch, and all the tests all traffic flows by a single  port , despite the four ports are on Chanel -group and port -channel mode is "on" that is, without LACP and have tested by load-balance the MAC and IP , and the result was the same.

Also have a HP software , IMC " Intelligent Management Center " and in view of the topology is shown the trunk between them but should indicate the link speed 4GB and 1GB is actually indicating .

How can I configure to use these transfers all ports , getting four ( 04 ) GB ?
Thanks

Cisco SG500X Channel-port has no performance

Hi,

You need to put the chanel-group in LACP under interface for example

int g1/0/26

channel-group 1 mode active

If you look into the state of interface you will see, in your case 2000 000 Kbits (this example it 2Gbps).

sw01#show interfaces po1

Port-channel1 is up, line protocol is up (connected)

Hardware is EtherChannel, address is 2401.c77b.1799 (bia 2401.c77b.1799)

Description: NEXUS

MTU 1500 bytes, BW 2000000 Kbit/sec, DLY 10 usec,

     reliability 255/255, txload 1/255, rxload 1/255

Encapsulation ARPA, loopback not set

Keepalive set (10 sec)

Full-duplex, 1000Mb/s, link type is auto, media type is unknown

input flow-control is off, output flow-control is unsupported

Members in this channel: Gi1/0/25 Gi1/0/26

ARP type: ARPA, ARP Timeout 04:00:00

Last input 00:00:00, output 00:32:24, output hang never

Last clearing of "show interface" counters never

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

Queueing strategy: fifo

Output queue: 0/40 (size/max)

5 minute input rate 46000 bits/sec, 66 packets/sec

5 minute output rate 4000 bits/sec, 3 packets/sec

     1025608725 packets input, 377125891927 bytes, 0 no buffer

     Received 509692687 broadcasts (85461812 multicasts)

     0 runts, 26 giants, 0 throttles

     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored

     0 watchdog, 85461812 multicast, 0 pause input

     0 input packets with dribble condition detected

     224105641 packets output, 106816187852 bytes, 0 underruns

     0 output errors, 0 collisions, 1 interface resets

     0 unknown protocol drops

     0 babbles, 0 late collision, 0 deferred

     0 lost carrier, 0 no carrier, 0 pause output

     0 output buffer failures, 0 output buffers swapped out

In your case should be 4000000 Kbits/sec.

Have fun,
