blank configuration for WS-C4500X-16SFP+ (Catalyst 4500-X 16 TenGig Fixed ports switch).
I would like to know how the port numbering is done (i.e. TenGig1/0/X or TenGig1/X or just Eth1/0/X ? )
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 ?
View 1 Replies View RelatedConcerning 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?

View 10 Replies View RelatedWe are planning for the first installation of 4500 switches containing these supervisor modules. I'm trying to determine the interface numbering convention for ports on the supervisors. Our existing 4500E all have SUP6 modules with twin-gig converters - so I am familiar with the numbering conventions used on those supervisors. How does this change with the software based selection command "hw-module uplink select" used in SUP7?

Note that these queues are numbered 0 - 3, and not 1 - 4. We've been assuming that the first queue number in the "mls qos" (i.e., 1) command maps to the first queue (i.e., 0) in the "show mls qos" command.
On the supervisor card of a cisco 6500 series, according to the following link, [URL] it only has 2 uplink ports on the card. Would I be correct in assuming that I only have those to ports that I can configure IP addresses on?
The cisco that is being devlivere is coming with a 48 port switch and 24 port fibre switch. Could I change any of those ports into a router port and configure IP addresses on those?
The supervisor card is a ws-sup-720-3b the 48 port switch is a ws-x6748-ge-tx the 24 port fibre switch is ws-x6724-sfp
I'm trying to enable port security on several 4507R's. When I try to configure a range of ports the switch will randomly put 1 or 2 in err-disable. It's different every time I apply the config to the same group of ports. However if I do them one at a time it seems to work. But I really don't want to configure 6 fully populated switches one port at a time. We also have a lot of 3750's and they gave me no problem using a port range. [code]
View 4 Replies View RelatedWe just installed a hosted VOIP system using Cisco 7900 series IP phones. We are having a strange issue with a few computers where they pull DHCP information from our VOIP provider's DHCP server on the Internet and not our LAN DHCP server.
The switchports areconfigured as: switchport mode access
My rationale behind this is that the phones would use CDP to get their VLAN info from the providers Cisco router and the PCs would just ride on the default VLAN. But this is not the case. Computers randomly keep getting DHCP info from the provider's router. Do I have to use voice vlan x and make the switchports trunks?
I have an all gigE 3560. I don't use the management FE0 port on the back. I was thinking to use that for a 100Mbps WAN connection.
Seems to work just fine when I plugged in an test. But I am not routing across that link yet as I still need to setup the far end.
Is there any reason this would not work? I would like to not burn a gig port if the max throughput of the circuit is 100Mbps.
I have a 3750g connected to a "core" switch stack of 7 other 3750g's via 2 GigE ports in a trunk. This is currently in a switchport mode access port- channel so only the default vlan data is sent over. Now we have a need due to physical location of these switches, to allow vlan20 (DMZ) from this 3750g to the switch stack. I will configure a few ports on the switch stack for vlan20 and they need to be able to talk to the stand alone 3750g.To do this I will change the port channel on both endpoints to
-switchport trunk ecapsulation dot1q
-switchport mode dynamic desirable
also making the appropriate change on the interfaces belonging to this trunk.My question is, now that its a trunk port that carries multiple VLANs, how much is the bandwidth reduced on that 2gbps link?I have a very active VLAN (10) on the stand alone switch, but on the core I'm not going to be assigning VLAN 10 to any ports. So does traffic from VLAN10 even come across the trunk (wasting bandwidth) if no ports on the core side are assigned to it? I really just need vlan 1 and 20 (for now).
is it possible to shutdown a specific port on my 3750x and monitor this port at the same time .for example , im dealing with a mac authenticated network using port security , i want to shut down all the ports that are not used at the moment , however , if some one gets connected to the one of the shutdown ports i want to know the mac address of the user or atleast to know that i have someone who is just plugged in to the one of the shutdowned ports .
View 4 Replies View RelatedI'm fairly new to Cisco products am in the process of developing my network knowledge on a deeper level. I have a 3825 with a HWIC-4ESW and I'm struggling to fully understand how the two "see" each other. I've setup a V LAN with a layer 3 address on the HWIC and added the switch ports to it. This seemed to allow devices connected to the switch ports to talk to the built-in router ports. I thought this was all making sense until i applied an access-list to the router port. It's a simple ACL i'm just using for testing and the only thing it does is blocks telnet from anywhere. I know the ACL is setup properly because if I connect a device directly to the router port i cannot telnet to the port. However, if i connect a device to one of the switch ports, i am able to telnet to the router port successfully.
It seems that I'm missing something with how traffic flows from the switch port to the router ports and how the two "see" each other.

We have a stack of switches that is at the max number of members allowed in the stack. Problem is we are running out of port density and need to add more ports. So instead of adding a whole new stack I would rather replace 2 of the 24-port swicthes with 48-port switches.
If the two 24-port swicthes we are removing are stack members and neither of them are the stack master, I should be able to replace the 24-port switches with the 48-port switches without bringing the master offline? If the new 48-port switches are running the same IOS version as the current 24-port swicthes, they should add themselves to the stack?Would I have to tell the new 48-port swicthes what switch numbers they are replacing in order for them to be added to the stack since we are at the max number of members?Also since the 48-port swicthes are replacing 24-port switches will the master give the 48-port switches the configuration for only the 24-ports?
My company uses Cisco 891's in replacement of the 1811 where we would have DBU used via an external modem and a triggered time of 3 minutes after a primary connection failure was identified. In testing the 891 in a Layer 2 failure environment, it is within milliseconds that the v.92 port is engaging after the layer 2 failure. Has anyone been able to get it to attempt at a more than millisecond rate?

I currently have a Cisco 891 running with a FTP running on port 21. I currently have the NAT from external IP to and internal IP 192.168.12.6 for port 21. And the firewall allowing that traffic through and client software is working fine. However I need this FTP to be running on port 990 and anytime I change the NAT and the firewall, the external FTP clients connect but then drop when recieving the directory listing.

I have an problem with my new Cisco 876 Router. I configured port forwarding to access internal network devices from the internet . This works good from external but with my old Fritz box I was able to connect to this internal devices from the same internal network with the dyndns address.
So here is a short review for this:
DYNDNS Address port tcp 80 - > 192.168.0.80 tcp port 80
from ex tern it works but with source address example 192.168.0.20 to destination DYNDNS address tcp 80 (maps to 192.168.0.80 tcp 80 ) it doesn't work. Is there any trick in the config of cisco to let this scenario work?
I need to configure the port forwarding on Cisco 887 to forward port 22 on Public IP to a LAN IP port 2200. I don't know anything on Cisco router at all, beside telnet to the cisco and quit . Any step by step command.
