Net/PC How to

When installing Epson LQ 570+ printer in Windows 10, you don’t see the printer driver. you need to download it form some websites. Also if the computer doesn’t come with the printer port, you can buy the USB to printer port cable.

Q: Our Cisco 2960-XR comes with 2 fixed 10 Gigabit Ethernet SFP+ uplinks. Can we purchase SFP ports to connect to out server with 10GB NIC? 

I search online and someone says: “The uplink port on the switch is usually a higher-speed port used to connect smaller local network to a larger network or connect to another higher-speed switches in the topology”.  My question is if we can use the SFP+ uplink ports as normal ports to connect our new server.

A: If both server and switch NIC are SFP, that will work. However, adding 10GB NIC on server isn’t benefits for the serve. 10GB is more benefits for SAN or accessing data storage.

if server not support SFP based NIC card, only option for you 1G X 2qty port  – Port-channel  2GB you can do.

If the uplink ports on the 2960-XR series switches are fixed, meaning if they are SFP+, they only support 10Gig optics and not 1Gig optics.

Make sure you enable QoS on those ports — because you will really, really need it.

Situation: The client configures dual site to site VPN connecting to AWS using two ISPs, AT&T and Comcast. They configure both Active-active load balance and failover. They would like to know how to switch between Balance and Failover.

Resolution: assuming both configuration are correct and they are using Active-active balance, you just need to check Fail Over under Monitor Profile by going to Network>Network Profile>Monitor.

Commit to save the change.

Q: We configure dual site to site VPN connecting to AWS using two ISPs, AT&T and Comcast. This is Active-Active load balance Tunnels. How can I test to make they are working?

A: You may have many options.

1. Use Paloalto firewall command: ping source IP host IP. For example if the AT&T local IP is 12x.x.130 and AWS private host IP is 10.2.2.35, run this command: ping source 12x.x.130 host 10.2.2.35. If the comcast local IP is 50.x.x.125, run this command ping source 50.x.x.125 host 10.2.2.35
2. You can disable one tunnel for testing another tunnel. Go to Network>IPSec Tunnel. Highlight one of tunnel, for example AT&T to AWS tunnel 1.

Click Disable. Click Yes to confirm disable the tunnel.

Commit to save the change.

Ping the AWS private IP address, 10.2.2.35. If it works, you are connecting the AWS using the different tunnel.

1. show routing route

For example

2. ping source IP host IP

3. traceroute host IP

4. test routing fib-lookup IP

blin@HSA-Firewall> test routing fib-lookup virtual-router default ip 10.2.2.36

---

runtime route lookup

virtual-router: default
destination: 10.2.2.36
result:
via 12.x.x.129 interface ethernet1/1, source 12.1x.x.130, metric 10

runtime route lookup

virtual-router: Test
destination: 10.2.2.36
result:
via 50.x.x.126 interface tunnel.100, source 169.x.x.250, metric 10

5. test vpn ipsec-sa

blin@HSA-Firewall> test vpn ipsec-sa

• tunnel test for given VPN tunnel
  | Pipe through a command
  Finish input

blin@HSA-Firewall> test vpn ipsec-sa tunnel
ADP-Tunnel:net1 ADP-Tunnel:net1

ipsec-tunnel-2 ipsec-tunnel-2
test for given VPN tunnel

blin@HSA-Firewall> test vpn ipsec-sa tunnel Comcast

Start time: Sep.25 19:03:48
Initiate 1 IPSec SA for tunnel Comcast.

Q: Is there a way to add Public Calendar into Favorites? I try it but the public Calendar doesn’t show up in the top of Favorites.

A: If you right click on the Public Calendar, you do have an option to add the Public Calendar ton the Favorites. However, it will show up in Public Folder Favorites, not the top Favorites which is Mail favorites.

You may drop the Public Calendar to the calendar if that will be easy for you to navigate.

The client has two ISP, AT&T and Comcast. They would like to configure fialover site to site VPN connecting to AWS. This article will show you how to configure dual IPSec VPN failover using Tunnel Monitoring on Paloalto Firewall.

The configuration is based on this topology.

1. Make sure you have Tunnels configured. Please refer another video for IPSec Tunnel Configuration.

* Login Paloalto firewall and go to Network > Interface > Tunnel 

* Network > IPSec Tunnels

2. There are two ways to do VPN tunnel traffic automatic failover:

1) Failover using Tunnel Monitoring – is used to make sure the VPN tunnel is passing traffic. If the primary VPN tunnel (1) in our example) goes down or if there are traffic issues over the VPN, the tunnel monitoring will detect it and will bring the primary tunnel interface down. Thus the route through the Primary tunnel interface tunnel 1 will be removed from the Forwarding table and the route through the Secondary Tunnel interface tunnel 100 will take over.

* To configure a Monitoring Profile.

Network > Network Profiles > Monitor > Add

Make sure “Fail Over” Option is selected.

* To enable Tunnel Monitor on the IPSec Tunnels

Network > IPSec Tunnels > Primary-Tunnel (1), make sure Enable is checked for Tunnel Monitor.

Configure the destination IP to be monitored and select the configured Monitor Profile “tunnelMonitor”. Note: if you don’t see Tunnel Monitor, click on “Show Advanced Options”.

Repeat above to configure the destination IP to be monitored and select the configured Monitor Profile “tunnelMonitor“ on Secondary Tunnel 100.

Note : For Tunnel monitoring to work the Tunnel Interface will have to be configured with an IP address. 
Once the Primary Tunnel monitoring on the Primary tunnel fails, the tunnel interface status is forced to Down.
Network > IPSec Tunnels.

Once the Traffic through the Primary Tunnel recovers, the tunnel monitoring will come up and the route through tunnel.1 will be installed in the Forwarding table.

Once the Tunnel monitor is goes DOWN or UP the below logs can be seen under System logsMonitor > Logs > System

2) For configuring Failover using Static Route Path monitoring, please view another article.
