View 1 RepliesI've just installed 2 of these in my workplace on a PLC network.I'm now looking to set one of the ports up as my diagnostic port and would like to be able to mirror any of the other ports to this port.I believe it is called SPAN on Cisco switches.The only reference I can find to it is configuring via Telnet which I haven't got a clue about.On my old Wiedmuller switches it was just a few clicks away.

How the port numbering would be on Sup 7-E and Sup 7L-E? I mean, on Sup-6E and Sup-6LE, if I used a twin-gig converter, I used ports gi3/3,gi3/4,gi3/5 and Gi3/6 [If the sup is in 3rd Slot]. I know there are now 4 ports on the Sup 7 which can either be used as Gig ports or TenGig ports. So, how will the port numbering change ?

I would like to know how the port numbering is done (i.e. TenGig1/0/X or TenGig1/X or just Eth1/0/X ? )
Concerning the WS-X4640-CSFP-E module, I was surprised to realize when I got it that the ports are numbered 1-80 rather than 1-40. Then I saw it is actually an 80 port blade when you use half-SFP's. But we have full SFP's, so how does it do the numbering? If I use all full-SFP modules, do the even-numbered ports just go unconfigured?

I'm looking at implementing a new DMZ and wanted Netflow capability for security monitoring.The architectural principles I have to adhere to dictate that the switches within the DMZ are layer 2 however to get Netflow I need a minimum of a 3560/3750X, Network Services module, IP Base IOS with ip routing and CEF enabled.To do this and still keep the switch functioning as a layer 2 device the intention was not to configure SVI's or any static/dynamic routing protocols.Will Netflow still work in that scenario?

We have noticed that when an EKG machine is plugged into one of the ports on some of these switches and the EKG machines are set manually to 100/Full, the ports are no longer usable until the switch is restarted. The switch is configured for auto. If the EKG machine is set to auto, it will work and not cause problems. The link on the interface will show up/up and there will be output packets increasing. However, there will be no inputs on the link and the port is unusable. Unfortunately, even when the device is removed, the port becomes unusable for any device. Is there any way to fix this problem without rebooting the switch?

When quoting a Catalyst 3750X with PoE (WS-C3750X-48P-E) the Dynamic Configurator Tool allows to include as the secondary power supply option the Catalyst 3K-X 350W AC Secondary Power Supply (C3KX-PWR-350WAC/2), but the default included primary power supply is the Catalyst 3K-X 715W AC Power Supply (C3KX-PWR-715WAC). My questions are the following:
1. Will this combination of power supply work?
2. Will the C3KX-PWR-350WAC/2 be able to power up the switch if the primary power supply of 715W fails?
3. Will the PoE will be lost if the primary power supply fails and only the secondary power supply of 350W keeps working?
4. If this secondary power supply of 350W is not suitable for PoE, why it is available as a secondary power supply option in the Dynamic Configurator Tool for a PoE switch?

I'm trying to work out if I need to order the "IP services" image for a couple of C3750-X. I need to run OSPF on these switches, but find the IOS image requirements on Cisco contradict.
At the top of the data sheet it says: • Open Shortest Path First (OSPF) in IP Base image
On the product info page it says: IP Base: Enterprise Access Layer 3 Switching, including OSPF (Open Shortest Path First) for routed access
But in lots of other places it says you need 'IP services' for OSPF.
As the IP services IOS is quite a bit more expensive I would like to avoid buying it. What image do I need to run OSPF?

I want to configure accesslists on my Catalyst 3750X-switches to protect different VLANs/networks. Any best-practices about inbound versus outbound accesslists? In my head it is more readable and easier to understand the config when accesslists are assigned outbound on the VLAN to protect instead of assigning them inbound on all possible source-VLANs. But of course, from a performance point-of-view it is better to use inbound access-lists to avoid un-necessary routing etc.

I know the catalyst is L3 but I am needing nat functions to get outside to the internet. From my 2800 series router I am able to ping out to the internet, also I am able to ping the vlan interfaces on the catalyst switch. Problem is from the catalyst switch I can ping the inside and outside address of the 2800 but I cannot get any further then that. I cannot ping the 2800 router gateway. Not sure what I am doing wrong as far as routing.

The 3560 switch is serving as an access and distribution layer switch. End devices are connected to it and it also implements IP routing via SVI and L3 ports.Auto qos voice cisco-phone has been implemented on applicable access layer ports. SRND4 is being used.
2960:
mls qos map policed-dscp 0 10 18 24 46 to 8
mls qos map cos-dscp 0 8 16 24 32 46 48 56
mls qos srr-queue output cos-map queue 1 threshold 3 4 5
mls qos srr-queue output cos-map queue 2 threshold 1 2
mls qos srr-queue output cos-map queue 2 threshold 2 3
mls qos srr-queue output cos-map queue 2 threshold 3 6 7
[code].....
Question 1:Why is the auto qos generated policed-dscp map different on these two switches?The Cisco Smart Business Architecture LAN configuration files guide [URL] does not specifically use the 3560 in their examples, they use the 3750 but it's my assumption that the same techniques, configs apply with regard to my specific feature questions. When using a 3750 in the Access layer, the guide shows (page 15) the same auto qos generated policed-dscp map configuration that is on my 2960. The SBA LAN config guide shows that when using a 3750 as a Distribution layer switch (page 26), the policed-dscp map configuration is the same that I see on my 3560.In the configuration guide for the 3750 distro switch, there is no auto qos applied as there are no access ports, so the mls qos commands are manually input. Since my 3560 does have access ports, auto qos generated the mls qos commands, and the results are the same be it following the guide and manually entering (per distro switch guidelines) or using auto qos. This leads to question 2...
Question 2:Why is the mls qos map policed-dscp configuration different depending on use as an access vs. distribution switch?
Question 3: On the 3560, access ports that have "auto qos voice cisco-phone" applied are put into queue-set 2 (output). Queue-set 2 (output) uses default values (not configured). Is this correct and desirable? If so, why? The 2960 has all ports in queue-set 1, regardless of being an access device port or a trunk port connected to the 3560 (as per the SBA LAN config guide EgressQOS macro commands). The 3560 trunk ports are all also configured to use queue-set 1 (output), again as per the SBA LAN config guide EgressQOS marco commands.

View 5 Replies View RelatedI have one specific trouble with Catalyst 3560CG switch and Stardom reserved industrial controller. Controller has 2 processors, one of them after(!) negotiation become main with IP 192.168.1.1, other one stays in reserve with IP 192.168.1.129. If main one shuts down, spare one becomes main with IP 192.168.1.1. This perfectly works with DLINK and MOXA level 2 switches, but fails with Catalyst 3560, because spare one cannot even connect to switch port. I don't know the exact reason of it, but i suspect, that it happens because of before negotiation both controllers have ip 192.168.1.1 (i know, that it is wrong and weird, but so it goes). First of them correctly connects to switch port, which goes up and passes pings. Second processor tries to connect to switch port, which goes several times up and very soon down, then processor lefts his tries to connect to anybody and become idle. The switch seems to some way check IPs of 1-st and 2-nd port packets, and shuts down 2-nd port. I have connected via hyperterminal and tried to disable some level 3 functions and checks of the switch, but this wasn't useful. how exactly(or at least approximately) should i configure a switch to make this bundle work?
