Nexus 5500 support auto negotiation on 1gig sfp port? There is an end device that only support auto negotiation and cannot be manually set speed/duplex.

We are facing to an annoying issue. We have a 6509 running in Catos 8.3(4) with WS-X6548-GE-TX, WS-X6348-RJ-45 and WS-X6148-RJ-45. When we configure the mode in auto negotiation, it comes up in half duplex. We need to configure the speed mode at 100Mbit/Full to make it work. But if the chassis or port restarts (not the server), the link becomes half duplex. This happens only on module in Gigabyte like WS-X6548-GE-TX.
Cable have been replaced but does not work. It is not happened on another chassis running on IOS 12.2(18)SXF17b with WS-X6548-GE-TX.
Does the Nexus 5548/5596 switch support OSPF ECMP?
Also on OSPF and ECMP, the load-balancing method at the multiple links for Catalyst 3750 is per IP packet or per destination IP?
confirm if "negotiation auto" is supported gigabit port for C3925E router.
Router(config-if)#Interface gi0/2
Router(config-if)#description test link
Router(config-if)# no ip address
Router(config-if)# negotiation auto

I have already exploited Metro Ethernet, but I don't understand why auto-negotiation does not support for Ten Giga ports?

This morning they replaced the switches and brought up the network, but here's the problem:1) Under the default card setting with Auto-negotiation, PC looks for DCHP Server address resolution and ends up with YELLOW triangle in the system tray.2) Whereas, when I CHANGE the card setting to 10Base in FullDuplex, then PC gets connected to the ISP network.ISP support said that either the card could be damaged due to lightning strike or it could be due to damaged cable running from port box to the PC (RJ-45). I'm wondering, could lightning strike damage a Network card in such a partial manner (just one feature, i.e., Auto-negotiation)? But that person warned, there will be deterioration in ISP speeds when I use 10Base in Full Duplex (for now) compared to Auto-negotiation speeds. Speeds really came down badly, that's understood.

View 3 Replies View RelatedIs there an official Cisco-Page with the always-up-to-date recommended NX-OS-Releases for the Nexus 5000, just as there is URL
If there is no such page: What Release can be recommended?
We got new N596 & N2232 this week, and are using L2-LAN only, no L3,no FCoE- or FC-Ports. The command 'vPC orphan-ports suspend' is the newest feature used, so 5.0(3)N2(1) would be the oldest possible release.
Before I install 5.1(3)N1(1a) and then have to do a distruptive downgrade to 5.0(3)N2(2b), I'd like to be assured that the new one is already recommended as mature enough.
How many VMs can a pair of 5548s support? Remember, for each VM, I will have an ARP entry in the 5500 ARP Table (assume 5500 is the L3 default gateway).

Are there any dependencies on VTP on the Nexus platforms like the 5500 or 7000? In IOS P V LAN required VTP Transparent mode however I cannot find any reference to this for the Nexus platform. Are there any other features that would require the use of VTP? By default VTP is turned off on nexus and has to be enabled with the feature command so is there any benefit to running VTP in transparent mode vs off?
View 1 Replies View RelatedThere is very little and quite diverse Information regarding the if, where and how of a Nexus 5000 or 5500 series Switch and support for IEEE 802.1AE Link Layer Encryption (also called MACsec).
For example: the official FAQ denies that the Nexus 5500-series supports 802.1AE at all, while the data sheet says that only "downlink ports" are supported (host access).
On the Nexus 7000 platform the 802.1AE link layer encryption is part of TrustSec (feature cts) and much better documented.
The Question is: If and under which circumstances (configuration, L3 modules, license, NX/OS version) does a Nexus 5k or 5500 series Switch support 802.1AE on 1G or 10G interfaces that are directly connected to a Nexus 7000 (with the necessary cts feature licensed/configured)?
I am experiencing inconsistent echo-replay from devices connected via VPC to Nexus 5500s while pinging from the Nexus exec prompt.
In some cases I receive normal response when pinging from one Nexus, but no response when pinging from the other switch. In other instance I receive normal response to one Nexus, and duplicate replays to the other. It looks like a VPC related bug. NXOS is 5.1.3.N2.1

I have a Nexus 5500 which is the core of our network and we have access layer switches uplinked to it. I know by default the qos markings will be trusted.
1. On a trunk uplink from an access layer switch to the Nexus, I have "mls qos trust dscp". Will the DSCP marking be preserved when it reaches the Nexus?
2. How do I do prioritization of voice traffic on an uplink on Nexus based on DSCP EF?
We have a switch that, when configuring auto qos on and edge port facing video equipment, the upstream port channel drops. I was wondering if no auto qos would have to be configured on the member ports of the port channel prior to enabling auto qos on any other ports.

View 4 Replies View RelatedI have a 4510R-E chassis with SUP7-E running IOS XE version 3.01.01.SG. I am unable to create a port-channel and apply auto-qos for VOIP.If I configure auto-qos on the physical interfaces, I get this message when I try adding them to the port channel:
"The attached policymap is not suitable for member either due to non-queuing actions or due to type of classmap filters."
Auto-qos is not an available command in the port-channel interface configuration, but if I try adding the service policies that were created by auto-qos to the port channel manually, it lets me apply the input policy but on the output policy I get this message:
"A service-policy with queuing actions can be attached in output direction only on physical ports."
With the input policy applied to the port-channel interface, I tried addign the output policy to the physical ports and I got this message:
"A service-policy with non-queuing actions should be attached to the port-channel associated with this physical port."
Is there a way to get the auot-qos policies applied to the port-channel properly?
currently nexus 2000 and nexus 7000 does not support dual connection. you can not connect to 1 nexus 2000 to 2 nexus 7000 chasis. But for the nexus 5000, you can. what is the problem to to support this feature on Nexus 7000s? 5000s and 7000s run same software.
