Ruijie NFPP Technology – can we limit SNMP, SSH, BGP is allowed only from specific IP addresses?
The NFPP can control the bandwidth data-flow won’t be so detail, it will control the IP, ARP or the DHCP which belong to layer 3.
Could You explain EVB/VEPA technology?
EVB/VEPA – Ethernet Virtual Bridging /Virtual Ethernet Port Aggregation is IEEE Standard 802.1qbg with is applied usually in Data Center environment, where Switch is connected to multiple servers with contain large number of Virtual Machines. This VEPA technology allows to bring Virtual Machine switching to physical switch (from vSwitch inside server software), with usually is much more advanced in security policies and features. Only requirement is that used virtualization software (VMWare/Parallels or other) need to support 802.1qbg. More info on this video: https://www.youtube.com/watch?v=48xi-luDT60
What is the packet buffer size in Ruijie 6220 series?
Ruijie 6220 Series Packet Buffer or Switching Cache is memory shared across all switch ports in order to deal with packet micro-bursts and its 9MB.
However, if we talking about FC / Data center environment – here is flow control technologies like DCBX in order to deal with bursts and en-shore lose-less Ethernet !
