Think about the word switchport for a moment. #switchport trunk allowed vlan remove 5-10,12 c3550(config-if)#switchport trunk allowed The no switchport command puts the interface in L3 mode (known as "routed port") and makes it operate more like a router interface rather than a switch port. After doing so, the EtherChannel had no ports assigned because the EC itself was still Layer 3. config the all physical member interfaces Be very careful with allowed vlan, it is absolutely important that you understand the difference between allowed vlan, and allowed vlan add. Ping, traceroute, EIGRP, iBGP peering is operational but no trunk details on the router side. If you had a layer 3 switch (which this is not), using the command “ no switchport ” or “ no switchport mode access ” would make the interface a layer 3 interface instead of layer 2. When you put an interface that is in Layer 2 mode into Layer 3 mode, the previous configuration information related to the affected interface might be lost. Chinese; EN US; French; Japanese; Korean The list of allowed VLANs does not affect any other port but the associated trunk port. . a. Prevents the interface from generating DTP frames. However all traffic to the switch management IP is then dropped only on that port until I physically unplug the cable and replug it. when i do . config-if. So lets say . Router(config-if)#no shutdown . That port can only be used for L3 communication, ie. A VLAN defined on that port is a subinterface without MAC-based forwarding to other ports using the same VLAN ID. 0 Should not be allowed on device (at least with both interfaces active) since network IP address ranges Hello Vikram, try to use directly the command. The ip address command assigns an IP address and network command that allows you to use the interface no switchport command (no mode access or anything else on the command). You can then apply an ip address to the interface. After you have configured a service instance on an interface, switchport commands are not allowed on the interface. End with CNTL/Z. native Set trunking native characteristics when interface is in trunking Be very careful with allowed vlan, it is absolutely important that you understand the difference between allowed vlan, and allowed vlan add. x. switchport mode trunk spanning-tree port type network speed 10000 vpc peer-link.

S1(config)# interface f0/1 S1(config-if)# switchport You have to already have a VLAN in the allowed list (not "all") before you can use the add command to append to the existing list. You can change it to a routed interface if you have enabled routing with the global ip routing command that allows you to use the interface no switchport command (no mode When using "no switchport" the port is converted into a layer 3 interface, which needs an IP address, and can't be assigned to a certain VLAN, as its now a routed port not a Solved: I am trying to add ports to vlan 1000 Vlan 1000 Name vlan interface Vlan1000 no shutdown no ip redirects ip address 10. Understanding the difference can make the difference between complete network chaos, and just simply adding a vlan. When I run switchport interfaces trunk, it shows that vlan 306 is allowed on that particu I´ve have this configuration but I guess is not allowing comunication on vlan 40. Index: 1 Feature: ipbase Version: 1. no shutdown 9. NewYork-Router(config-if) #ip address ? % Unrecognized command. Buy or Renew. N7K2# conf t. It is normally used when I have a port-channel setup as a trunk with allowed vlans, however when i do a show interface trunk it shows no allowed vlans can someone tell me why ? ! interface Port-channel128 description switchport trunk allowed vlan 2,201,208,253-255,705 switchport mode trunk ! ! interface GigabitEthernet7/ The port Fa0/2/0, corresponding to an interface on module switch (ISR4431-X-4x1GE), ports of this module only accept configuration like switchport mode access or switchport mode trunk, if you need use a port of this module, you can put once port at mode access and create a SVI o configure the port like trunk and equal you need configure a SVI to get remote Lesson learned: Make sure the interface is in the correct VLAN. (routable links) A L3 switch as more ports than a router and traffic is not using the same link. The list of allowed VLANs does not affect any other port but the associated trunk port. But the untagged traffic does not get tagged as 100. Range: 1 to 4040. You can use this command only when the interface switchport mode is access or trunk.

Dell# show interfaces switchport gi 1/0/1: Display information about the port to verify the switchport mode The list of allowed VLANs does not affect any other port but the associated trunk port. This interface is called Po10. Note: In this example, interface ge1/0/25 belongs to Here I just configured the port as dot1q trunk, no other additional command , is the switchport trunk allowed vlan needed in this interface configuration ? what should be the advantage of giving switchport trunk allowed vlan in trunk interface between two hsrp routers ? need help. Refer to the exhibit. I have this problem too. Step 4. interace gi x/x - x/x where the port connected to device. 1 Switch(config-if)# no switchport trunk allowed vlan 100 4. 2/30 interface port switchport mode trunk no shutdown! interface GigabitEthernet3/9 description L2 trunk GCW 5E switchport switchport trunk encapsulation dot1q switchport trunk native vlan 99 switchport trunk allowed vlan 1,37,121 do is add a vlan to the trunk on the etherchannel then all that needs to be done is on each "int port-channel X" add "switchport trunk allowed vlan add I attempted to create a routed interface using a port-channel interface in PT, but did not get the L3 options after configuring "no switchport". Solved! Go to Solution. Labels: Labels: LAN Switching; Solved: I have trunk port between two swithes, bot are in same vtp domain, and I cannot put switchport trunk allowed vlan command on port. When you use the no switchport command, all the Layer 2 configuration is deleted from that interface, and the interface has the default VLAN configuration. It seems that you have a layer 2 switch in hands, which is As a best practice, do not add the ingress VLAN ID to the switchport allowed vlan-list under the interface. 255. 1Q and ISL). i used a crossover cable in port 1 on both switches. It only works on switchport access vlan 304. Labels: Labels: Other You use the no switchport command to bring those interface from L2 to L3 interfaces. After commande there is no this command in config, and when I look at port with sh int x/x trunk, also nothing On a L3 switch, does no switchport take the place of ip routing? If I have ip routing disabled, and go to interface g1/0/5 and run no switchport there, and assign an address, will it have the same effect? (route traffic, etc. 800s are routers with extension lan modules so there known just to be layer 2 only , but on say a l2/l3 switch 3850 you can check the comamnds and also check can you make it a layer 3 port with no switchport. 4. bin. Switchport mode issues. Regards If the command no switchport access vlan 30 is entered on the Fa0/11 interface, what will happen? Port Fa0/11 will be returned to VLAN 1.
