Distributed Trunking was a means on the ProVision family of HP Switches (35xx/54xx/62xx/66xx/82xx.. not 38xx) to be seen as one switch. It was still two configurations, and there are some features that get disabled on the ProVision switches if enabled. When Distributed Trunking first came out, it was Server to Switch. Its since been improved from switch to ...

In the virtual switch properties you can set a VLAN ID for the host OS:

A lengthy solution ... So I've been toying around with different concepts and I think I've made a workable solution. Basically, there is a main bridge trunk (bt) that eth0 belongs to. Then for each firewall VM has its own bridge. bridge name bridge id STP enabled interfaces bt 8000.002618895a72 no eth0 ...

Unfortunately, your goal of adding bandwidth really won't work the way you expect. See: VMware NIC Teaming - How to gain more than 1Gbit/s copy speed between two VMs? If more bandwidth is required, you'll have to move to 10GbE networking.

the stacking ports are full duplex so a single cable completes the ring. A hmdi plug is probably stronger than a LC fibre plug, but as the HDMI loop is in the rack (I doubt you could run a 10m HDMI and have a working stack) strength/latching capacity it a bit irrelevant. I would say, having bought stacking kits in the past for several hundred pounds a £3 ...

Q: Can layer 2 switch ports be configured as VLAN trunk ports? A: Most certainly. VLAN's are a Layer 2 construct. Q: Do I have to set both ends of the trunk as a trunk? A: Yes. A few things to note: You need to make sure that both sides of the trunk have the encapsulation configured as 802.1Q. I can't give you specifics on how to configure the trunk on ...

You can do either with recent kernels, there is no appreciable difference in efficiency. Personally I find the idea of putting a VLAN interface into a bond to be weird, if you want high availability then surely you want it for the whole physical interface then sort out VLAN tagging later, but enough people asked for it that it's a thing now.

The short answer is No, it doesn't. Let's be clear what we're talking about. When people use the term "bandwidth," they can mean several related but separate things: The port speed is determined by the physical hardware. A gigabit Ethernet port means just that: a bit of information is transmitted every 1 nanosecond, or 1 Gbps (I know I'm simplifying ...

Can you unhook an (active) interface from a virtual switch without disrupting traffic? Yes, you can, assuming there's another uplink available to that vswitch. Can the network configuration be inconsistent across a cluster (not using HA) without causing global problems? Yes and no. You need to make sure your vmkernel interfaces are reachable. You ...

Serving DHCP settings for multiple VLANs is not mainly a port trunk issue. A DHCP client sends broadcast packets to find a DHCP server that will respond to this request. When multiple VLANs are configured, broadcast traffic will not be forwarded to other VLANs. So your DHCP Client won't be able to find a DHCP Server on another VLAN. The proper way to ...

Scenario a) It leaves g1 untagged. Scenario b) Again, untagged. The switch will strip the VLAN tags when packets leave on an untagged interface.

It looks like the answer is "yes," but I suspect that doesn't fully meet your needs. I found a manual here [ https://eu.dlink.com/uk/en/-/media/business_products/des/des-1210-series/manual/des_1210_series_c1_manual_v4_00.pdf ] that has relevant information. The configuration you are looking for isn't covered in detail in that document, but page 38 ...

To undestand that, it is important to understand the concept of VLANs. Typically there is often a tagged VOIP VLAN and and a untagged Network VLAN on Office LAN connections. The wireing is through the phone ports just needing a single cable for two different LANs. The PC is then connected to the phone. On the switch side a trunk port is often configured ...

LACP is negotiated link aggregation (LAG) using a protocol. It needs to be actively supported on both sides. If one of the sides doesn't support LACP the trunk doesn't come up and you've got two separate ports. If the modem uses a simple switch for both ports (plus the internal one) and there's no spanning tree protocol running, this effectively creates a ...

Since you've got redundant links, (R)STP is required. You need to select a root switch and set it to low STP priority (otherwise the root switch is rather random and can lead to frequent reconvergence and flapping ports). With redundant links, ONLY set up an aggregation trunk when all links run between the same two switches. Trunk groups with more than two ...

Trunking means allowing multiple VLANs via one physical or LAG port. I've read documentation and decide that Level One GSW-2476 switch doesn't support LAG. Also it doesn't support STP and loopback detection. May be you had network ring issue. If you want to use LAG between servers, then use it as RoundRobin method via VLAN per port.

So first, what is your native VLAN ? I'll identify it by ~native~. You need to set the port 10 as on the vlan 1940 #conf t (config)#vlan 1940 /* description of VLAN as you want */ (config-vlan)#no shutdown (config / config-vlan)#int f0/10 (config-if)#switchport mode access (config-if)#switchport access vlan 1940 /* Verify */ #sh vlan brief Now, will ...

Do you have a route between these two subnets? The 192.x subnet needs a route to your 172.x subnet and vice versa. Also if both VLANs would be in the same range you need also a route, because the interfaces works in different separate VLANs without routing - the devices will ignore each other.

LACP might help you. However, you won't get more than 1 Gbit/s for a single connection. That's because LACP chooses the uplink to use through a combination of different parameters. If source and destination MAC, IP and port stay the same LACP will always use the same uplink. But LACP can give you more overall bandwith. Btw: your virtual switch is ...

Had my PVID settings wrong. I knew it was just something simple again. Hope this post + pictures helps someone else out in the future. Here are two more screen shots showing the correct PVID settings and the resulting final port list. Cheers Wireless Access Point

This is a know bug from Asterisk when you use the non standard sip port 5060 for your server. The bug is discussed here https://issues.asterisk.org/jira/browse/ASTERISK-24767 . You should be able to correct this using fromdomain=prepago.com.py:5060 but Asterisk ignores the directive port and rewrite the from as From: "sip:595212376741@prepago.com.py:5061". ...

38 503 NETWORK_OUT_OF_ORDER network out of order [Q.850] This cause indicates that the network is not functioning correctly and that the condition is likely to last a relatively long period of time e.g. immediately re-attempting the call is not likely to be successful. My guess is that your Caller ID is offending them. Are you setting to anything ...

a trunk port is required to forward multiple vlans between switches. each ethernet frame is tagged with vlan membership. The trunk port is configured with 802.1q encapsulation to carry the vlan membership in an Ethernet frame.

ON the AP side, it is missing encryption config for the 2nd SSID: encryption vlan 2 mode ciphers "something" On Router side, You left out the NAT configuration for the guest network. Having pointed out the above, it may still not work. I have the same configuration. the "ssid2" clients will associate but can not get IP address from the DHCP. I'm looking ...
