When I'm doing small pings everything is fine but when I do ping -i .2 -s 1300 or higher packet loss starts to get out of hand like 20-30%. It results in terribly slow loading for some websites, especially LAN services. When I skip CRS305 and connect directly to CRS317 OR use "auto-negotiation=no speed=1Gbps" between CRS305 and CRS317 then everything is fine (also when I skip CRS305 completely).
So it seems that CRS305 has some issues with handling 1G / 10G forwarding that doesn't seem to be an issue for CRS317 nor CRS326 (used in other part of network). Is it known problem for this small device? Are there known solutions? I'm using this switch in quite straightforward fashion:
Code: Select all
/interface bridge
add name=br-hardware protocol-mode=none vlan-filtering=yes
/interface ethernet
set [ find default-name=ether1 ] name=ether1-rescue
set [ find default-name=sfp-sfpplus1 ] auto-negotiation=no l2mtu=9112 mtu=9000
set [ find default-name=sfp-sfpplus2 ] auto-negotiation=no l2mtu=9112 mtu=9000
set [ find default-name=sfp-sfpplus3 ] auto-negotiation=no l2mtu=9112 mtu=9000
set [ find default-name=sfp-sfpplus4 ] l2mtu=9112 mtu=9000
/interface vlan
add interface=br-hardware name=vlan10-ccr vlan-id=1030
/interface bridge port
add bridge=br-hardware frame-types=admit-only-untagged-and-priority-tagged ingress-filtering=yes interface=sfp-sfpplus1 pvid=410
add bridge=br-hardware frame-types=admit-only-untagged-and-priority-tagged ingress-filtering=yes interface=sfp-sfpplus2 pvid=411
add bridge=br-hardware frame-types=admit-only-untagged-and-priority-tagged ingress-filtering=yes interface=sfp-sfpplus3 pvid=412
add bridge=br-hardware frame-types=admit-only-vlan-tagged ingress-filtering=yes interface=sfp-sfpplus4 pvid=5
/interface bridge vlan
add bridge=br-hardware tagged=br-hardware,sfp-sfpplus4 vlan-ids=1030
add bridge=br-hardware tagged=sfp-sfpplus4 untagged=sfp-sfpplus1 vlan-ids=410
add bridge=br-hardware tagged=sfp-sfpplus4 untagged=sfp-sfpplus2 vlan-ids=411
add bridge=br-hardware tagged=sfp-sfpplus4 untagged=sfp-sfpplus3 vlan-ids=412
MTU on interface doesn't seem to affect problem, I'm getting the same packet loss no matter what MTU I set on laptop (for 1300 packets). However of course the higher packet size is, the bigger loss. With 8k packets (when MTU is set to 9k) I'm getting like 50% packet loss.
