View 2 Replies View RelatedI'm in the middle of a Nexus 5000 project and recognized today while configuring port-channels, that some of the interface numbers are reserved for internal use.
Is it possible to change or configure which port-channel interface numbers are allocated for internal use by NX-OS?
Unfortunatly I wasn't able to find a solution for this issue in the offical Nexus documentation, the search function of this forum or Google. If I did miss something or didn't look careful enough at the Nexus docs, I'm also happy with RTFM (... fine manual) responses and links to the info :-)

I think I may have a bad port on a 5548, does the NX-OS has any sort of self-diagnostic test on its port?
View 6 Replies View RelatedSo I took a laptop with wireshark and plugged it into a nexus 5000 port that is configured as a trunk with 3 vlans allowed on it. The laptop was seeing all kinds of traffic on the wire, most of it was not involving my laptop.
For example: Server A VLAN 10= 10.10.10.1 Server B VLAN 20= 10.20.20.1 and wireshark laptop is plugged into a trunk port which is allowing those vlan's. The vlan's are routable.
10.10.10.3 is seeing the entire conversation when 10.10.10.1 backs up 10.20.20.1 even though it has no reason to see it. It is as if the trunk is spanning traffic to the laptop port. No span is setup however. It's really weird. This is not just broadcast traffic, but actual tcp taffic between Server A and B. Why would a trunk port see traffic between 2 other servers talking to each other on the vlan.
Trunk port configuration below:
Interface Ethernet 141/1/3
switchport mode trunk
switchport trunk allowed vlan 10, 20
I have configured my Nexus 7018 and 5548 as follow (see diag attached).Both 7000 and 5500 are vPC pair(po1and po2). Now I have created port-chanel between 7018and 5548 as port channel PO3 on 5500. Would it give me 20g bandwidth as PO3?or 10g only uplink to 7018? Do I need to config all four 10g links in PO3 on both 5500 and 7000 switches to achieve max b/w and failover?

I am trying to create a port channel between HP servers (4 nic) and two nexus 2k. The server side its a single team with 803.2ad fault taulerence and on the nexus side it have created two port channel (port channel 1 for nexus 2k1 and port channel 2 for nexus 2k2) and made them ACTIVE (channel group mode active)
But when i add a another server on different ports and port channel them the same way as the above server on nexus 2k1 and nexus 2k2, the first server stops pinging. so i have to sht down the first port channel and reopen them - then it works, however it says NO NETWORK ACCESS on the servers (running windows 2008). the only way is to reboot the server i cant be doing this on a production network.
I am having hard time in understanding the hardware port channel resource concept in Nexus 5Ks. Which scenario is considered as a hardware port channel and which is not. According to Cisco documentation, 5548UP switch with layer 3 daughter card only supports 8 hardware port channels, does this mean we can connect only 8 dual homed Fex to those 5Ks.Will a dual homed fex consumes a hardware port channel?
View 4 Replies View RelatedI am a bit confused by the output of 'show run' and 'show run switch-profile' that pertains to a port-channel interface configured in a switch-profile. My main gaol is to find out how can I add/remove the allowed vlans the port-channel (configured as trunk) carries. The setup is like this. I have 2 N5k in vPC domain and Etherner1/11 on both switches is configured as trunk vPC that connects to a core switch. When I issue ‘show run’ for the port-channel and physical interface I get the following output. [code] From above it seems the switch-profile configuration is missing the 'switchport trunk allowed vlan' in the port-channel interface. If want I to remove vlan 30 from the allowed vlan, should I go under the switch-profile mode and remove vlan 30 from the allowed list even though the switch-profile configuration seems to be missing this.

I have a router on which I would like to create a port channel that spans two different Nexus 2248TP switches, and then create a couple subinterfaces on the router's po interface. I've done this successfully on my primary router, but the config doesn't seem to work on the backup router. The primary is running IOS 15, while the backup is running 12.4.25d advanced IP. I do see the trunk come up from the switch side, and my router subinterfaces and po interface show up, however I'm not able to get anywhere from the router. It's not even able to reach other hosts on the same network. As soon as I remove the port channel config and use the physical interface and assign the same address used on the port channel interface, everything works as expected and I have connectivity.

We are using two N7K's to which is one N5K connected through a vPC. From the N5k we use a port-channel with 4 * 10G. Two of this four ports are connected to on N7K and the other two are connected to the other N7K. On the n/K's we are using vPC.
My question now are:
1. Where i have to connect the policy map? To the port-channel or on each physical interface?
2. When i have to connect this policy to the port-channel, how does i have to set the shape percent, when i would like to reserve 10% from the 40G? Does i have to set the shape value to 5% on each N7K because vPC?
if I can use the encrypted port as unencrypted ethernet ports? url.. Each individual port on the Cisco Nexus 5010 switch is numbered, and groups of ports are numbered based on their function. The ports are numbered top to bottom and left to right.There are 20 to 28 ports on the Cisco Nexus 5010 switch, depending on which GEM is installed.
The 20 fixed ports form group 1 and are named 1/port_number. Ports 1 through 16 are unencrypted Ethernet ports. Of these, ports 1 through 8 are 10-Gigabit Ethernet and 1-Gigabit Ethernet-capable ports. Ports 17 through 20 are encryption-capable Ethernet ports.

View 3 Replies View RelatedI understand you can't assign an IPv4 Address to a "port". But here's my issue. I have two network cables attached to a managed switch, the location of the two cables are very important. Two computers attached to the said cables.I would like to communicate with one of the computers on PORT 1 and PORT 2, regardless of what computer is plugged into them. They get there IP's via DHCP, and a static IP wont work - as the computer plugged into PORT 1 or 2 may be different.So. I have two ports on the switch that I always want to communicate with the computer on the other end. But I don't (will not) always know the IP address of the computer(s) connected.

Thing is I have only one 24 bit public Network ID provided to me by ISP. One IP address of the range is used for ISP's gateway. So I have 253 addresses to be distributed among divisions. However to avoid IP address conflicts I have to be sure that only dedicated for a division IP address/es is/are used by the division.

Actually i have 7600 router and all trafic passes through Gi0/1(Routed port) interface to 6500 series switch. I need to create a vlan on this router eg. vlan 10 Any how it is possible assign a vlan to routed port and traffic of wan interfaces and the vlan traffic passed together.
View 2 Replies View RelatedSo I have a current port-channel between two 6ks that I need to upgrade. There's too much traffic and the port buffers on the SUP7203B sort of suck. Microbursts are causing overruns like mad. Im going to move the 2x1gig port-channel to a 6724 and make it a 3x1gig port-channel. The switches carry production traffic across the link to the tune of about 400 meg during the lowest load time. Initially, I thought that I couldn't move the port channel without temporarily taking down the link but I think I have a workable solution now. Has anyone done this successfully before? Im curious what others have done. Also, to make matters worse, the existing port-channel is 'mode on' and I want to migrate to 'mode active' in the new channel
