have been eliminated, you can switch to the standby device through NSRP to restore the network operation and further locate the hardware failure. The switch mode is 1, unplug the upper and lower line network cable of the main firewall (only if the device is powered off, you need to unplug the HA connection of the device), the firewall will automatically make the primary standby

A device that analyzes traffic has been deployed in the previous period and needs to mirror the port's traffic to a single copy of the server's NIC.Because the Juniper Operation command is unfamiliar, the online command is also relatively few. So write a blog record.EXthe port mirroring of the switch allows the port to be in traffic, or the outbound traffic is mirrored separately, andethernet-switchingof th

Okay, everybody.This weekend seems to have been very fast, because there are too many customers after-sales problems need to actively cooperate with the processing, in short, the time for engineers to do a good job of technology has gone, many times we have to assume too many original role, and not just Huawei, China three, Cisco.this share, but also focused on the configuration of the idea of Huawei, rock Mesh firewall

In the front I sent an article "Juniper Firewall diagram L2TP VPN Configuration", we learned from that article how to configure. But we know that the L2TP VPN is only connected to our L2TP VPN server, but it doesn't encrypt our data, and we know that IPSec's data is encrypted, and if the IPSec-unaware friend can look at my previous IPSec VPN concepts (i) And the concept of IPSec VPN (ii) to understand. Okay
