I have Cisco 800 series (888w) with BRI-ISDN port. Is there any way to change the usage of ISDN port to normal RJ45 port?I want to use this SOHO router to sharing connection.
View 0 RepliesOne of branch locations has a Cisco 1941 Router . The port details are as follows
-Gi0/0 - ISP line
-Gi0/1 - Inside Network ( To a 2960 Switch)
Now they have procurred another line from ISP through which MPLS based VPN to the Main location is configured. What are the options I have , to terminate it on the Router ? As all the On board LAN ports are filled I guess I wont be able to do anything with the current setup .Are Switching modules available ? What is the Embedded-Service-Engine0/0 port that I see on #sh ip int b output ?
We have recently purchased 2 x 4900M switches with the following configuration:
2 x X2-10GB-SR installed in port te1/1, 1/2 (optical)
1 x 20 x 1GB RJ45 installed in the top left of chasis ge2/1 - 2/20
1 x WS-X4908-10G-RJ45 8 port 1/2 card in the top right of chassis te3/1 - 3/8
We have te1/1 connecting the 2 switches, and various vlan's and connections on the 1GB RJ45's with no problems.
However, we have a number of 10Gbps BaseT connections te3/1 - te3/5 which are causing us issues. On a reload of the switch or removal / re-install of the cable it can take anywhere up to an hour for the port to become active again. So when we reload the switch, we may get a connection come up after say 3 mins, but the port next to it may not come up for 15-60 min. The cabling is all the same (CAT6 and has been tested/verified) and all connections go to Broadcom 10Gb cards in Dell 820 servers running vmware. We have the following set on the ports:
switchport mode access
spanning-tree portfast
No speed or duplex can be set on these ports - these options are not available in the config.
Once a link is finally established, it will hold the link solid with no problems, but this is a problem for us, we can't have a reboot take an undetermined amount of time for the link to come back.
We have a new stack of two Catalyst 3850-48T's running IOS XE 3.02.00 (we are upgrading to 3.02.01 this weekend.)We noticed the CPU usage is around 30% even when there is almost no traffic going through the switch. We haven't seen any indication that it is causing a problem, but is this considered a normal baseline?I attached my config (with passwords sanitized,) show ver, show controllers utilization, and show process cpu history.
I noticed this behavior is normal on 2900XL/3500XL switches, but I didn't find anything relating it to 3850 switches. Does the same thing apply to the 3850 switches? [code] url...

Is there any way to change the port that is used for syslog messages on a Cisco 9500 switch?By default this is set to UDP port 514.There doesn't seem to be a command to change the port.

I have several closets with Cisco 3560 on the edge that I'd like to change the vlan that's used for the management vlan on each. In the core I have a Cisco 6509 with Sup720's.
I'd like to do this by changing the native vlan on the trunk port on the core 6509 interface that connects to the 3560. and leave the management vlan on the 3560 as vlan 1.
Seems trivial but what I tried didn't work and I didn't have the window to troubleshoot. I'll paste the simplified configs for the interfaces below

I have 2 x 3750 stacked, the port number of the master switch is gigabitEthernet2/0/1, slave as gigabigEtherent1/0/1.
Can I change the port numbering so that the master switch gets GigabitEthernet1/0/x?
So here is my network.
ASA5505--->Cisco1841--->Cat2960
Code
ASA asa831-k8.bin
Cisco 1841 c1841-adventerprisek9-mz.151-4.M2.bin
Cat 2960 c2960-lanbasek9-mz.122-55.SE1.bin
and here is my dilemma.
I can SSH from the internet to my ASA on default port 22, directly to my public IP. I can SSH from the internet to my Cisco 1841 on port 2001. I can not however, SSH to my Cat 2960. From what i can tell, on the Cat2960 i can't change the default port 22 for SSH to different port, just like i did on the Cisco 1841. I looked to see if I can change the default port for SSH on he ASA, it does not look like this is an option.
The bottom line is that i want to be able to SSH to all three devices from the internet. I only have one public IP. As of now, what i can do is only SSH to the ASA on default port 22 directly to the public IP and Cisco 1841 on port 2001. It appears that changing the default SSH port on Cat 2960 is not an option. It also appears that I can't change the default SSH port on the ASA, if i could, i would and then i should be able to SSH to the Cat 2960 on port 22. No matter what i did on the ASA, it always listens on port 22 for SSH connections.

how do i make it listen on different port?

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.
I was looking for a way to connect an AUX port from a 1700 router to a 6500 switch module console port, to see the output of the Switch's on the 1700 router, in case there is a network downtime, I could see what's going on in the switch, what cable should I use ? Also, is there is any kind of documentation for this type of config what have I seen is very few info.

View 1 Replies View RelatedWe 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?
