Cisco Switching/Routing :: Create A Port Channel Between HP Servers (4 Nic) And Two Nexus 2k?
May 9, 2012I 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.
Cisco Switching/Routing :: Nexus 5548 - Hardware Port Channel Resource
Mar 30, 2012I 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?

Dec 4, 2012I 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.

Jan 29, 2013I need to tear down an existing port-channel on a 3750X running c3750e-universalk9-mz.150-1.SE3.bin. This port channel is currently down down. It has three ports in it that will be added one each to three existing port-channels, I am assuming as long as the "channel-group" command is exactly the same as it is on the three existing port-channels I should be ok just adding the new port. One point to note is that the three existing port-channels all have three ports so this will be adding the fourth port to each port-channel. I know after reading that it is a best practice for load balancing to use either 2, 4, or 8 ports for a port-channel. Also what is the command to see all ports that are in a port channel?

Jan 3, 2012I'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 :-)

Cisco Switching/Routing :: Create A Port Channel That Spans Two Different Nexus 2248TP Switches
Oct 20, 2011I 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.

Now I want to make ether channel on switch 1 whcih has 24 fast etherenet ports. Can I make port 1- 8 as one ether channel which are connected to users or i can only make ethere channel of ports that are connectd to other switchs. If I can, how the other switchs will comnicate with the switch ports bundalled in the ether channel in switch 1.

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?

View 2 Replies View RelatedCisco Switching/Routing :: Configure Port-Channel Or Physical Interface On 3750
Jan 12, 2012how to configure this. I did it in the past but kind of forgot how I did it.I have a stacked 3750 (two physical switches) connecting to a 2960.
I am creating trunk ports with limited access to VLAN 300, 600, and 700.
There is two interfaces connected from the 3750's(one on each physical stack member) to the 2960.I have the physical interfaces configured exactly the same.
3750 Config:
interface Port-channel2
!
interface FastEthernet1/0/46
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1, 300,600,700
switchport mode trunk
speed 100
[code]....
Should I keep the configuration on the physical ports and not configure the Port-Channel Interfaces? Do I need to configure port-channel load balancing? Is the channel-group mode sufficient? Goal is to basically create 2 links to the 2960 to double the bandwidth and provide redundancy.

Cisco Switching/Routing :: CR3845 Internal Switch Trying To Configure 2 Ports On Same Subnet
Sep 6, 2012Have our public IP address space masked on /24 at our Internet Router. The router portion of 3845 connects to Internet, while the internal switch connects to my internal network and seeds it with the public address space. The switch had a port configured no switchport (L3) with an ip address with /24 (ie 67.63.145.1 /24) this connects to internal IPS/IDS then to Firewall which NATs to internal, then packet shaper, web filter etc etc etc. I need to test my ISP speed so I need to "break in" to the link between the switch and the IPS/IDS. I figured I could configure another port on the switch on the 3845 but my problem is the port to my network is routed and is masked on entire /24. I tried to configure a port on VLAN 1 and give myself an available address in the L3 address space and this did not work (figured it would not but gave it a try)
Any way to get two ports configured to use the same subnet while one is a L3 routed port and the other is just part of that layer 3 routed network?

The switch is configured with about 10 vlan and it is a inter vlan routing, a default route is configured in the switch where the gateway is the firewall.
