I would like to know why Cat3550 SVI's mac address is always same.for example if I configure interface vlan1 and vlan2.mac address is same as like 000d.bdfc.xxxx but Cat3750 is different, each SVI has unique mac address.
View 1 RepliesI faced with a strange behavior of ME3600.For testing purposes I linked Cat3550 and ME3600 switches via trunk mode. All interfaces are in Up state. But I couldn't ping SVI200 of Cat switch from ME3600 and vice versa. [cde]
This scheme perfectly works with another L3 swithes. For example Catalist3750. I know that ME doesn't support VTP, DTP and so on. Also, I've tried latest software.

View 1 Replies View RelatedLooking at the specs for the 3750 power supply - is the WS-C3750X-48P-S model with the 715W power supply referring to the amount for both power supplies per switch or just one power supply per switch? Meaning, is the 715 a accumulative number or, just the watts of one power supply. I would like to purchase a 3750x PoE switch with redundant power supplies. If this model is not the correct one?give me the model that offers 48 port PoE with redundant power supplies?

The rest of my internal network is 10.10.10.0/24. There are four other WAPs on the 10.10.40.0/24 network that I did not configure. When I assign an IP address - 10.10.40.7 to my WAP with the gateway as 10.10.40.100 (router), I cannot ping anything. If I assign the WAP an IP address - 10.10.10.192 with the gateway 10.10.10.100 (router), I can ping everything.

In other words, is there a specification or even just a set of values that define the default inspection parameters for all protocols? With DPI I can manage 'some' of the inspection capabilities but I have some fairly rigorous and specific requirements to meet and I need to validate that the IOS ZBFW will meet those requirements. Specifically, I'm interested in HTTP, DNS, and ICMP but all other protocols would be useful as well.I'm working with basic routers; 871's, 2811's, 1841's, etc. The IOS in use in most cases is adventerprisek9-mz.151-3.T.

View 7 Replies View RelatedWe have a Router with one External IP and a couple of VLANs. We have got a Teleconferencing Unit that needs almost every port known to man to work, so decided to get the unit its own External IP.
We have the IP now and how to get it in the router and then also to use it only for the Video unit (From outside straight through to Video).
Im comfortable adding lines to the router but just don't know what the lines should be.
The new IP's purchased are 116.199.222.200/30 (Only need to use one address, lets say 116.199.222.200). No idea what the subnet mask should be...

View 3 Replies View RelatedI'm fairly new to Cisco configuration and I am looking at a problem for a client that involves the use of a Cisco 887 (wired only) as the main router/gateway. The problem I am investigating involves the allocatoni of DHCP addresses from the device to a product we have designed that connects to the router. I am attempting to set the 880 up on the bench with no ADSL connection and just use the DHCP feature of the box for the 4 switch ports on the back. I have tried all kinds of configurations from default. Whatever I do I can't get the router to assign an IP address to anything that is plugged in (Windows or Linux machines). What could I be doing wrong ? It can't be that difficult to get the system to just act as a DHCP server.

I have issued the no shut command several times, but doing "sh ip int brief" it keeps showing up as administively down.
View 13 Replies View RelatedI would like to enable port security to hardcode the MAC address on the ethernet switch. There are 5 ethernet ports in the same ethernet switch to be assigned for one person (one note book), e.g. port 5, 6, 15, 16 and 23. The model of ethernet switch is cisco 2960S and one MAC address is configured on 2960S.
1. Does 2960S support this requirement to allow input the same MAC address to 5 different port?
2. If yes, can ethernet switch "smart" enough to forward the packages to "active" ethernet port which is connected to notebook and the rest of four ports are inactive.
3. if no, any solution or any work around to achieve this requirement
The customer has 4 6500 switches. 2 Physical locations, and 2 switches at each locations. The locations are connected via 1 200mpbs metro ethernet(layer 2). We ran into an issue during a DR exercise. We had created a VLAN for DR testing purposes, that did not have any SVI configured, but the VLAN did exist on one of the 6500s. When the customer restored a VM to the DR VLAN, we lost connectivity to the production server. After some troubleshooting, we found the cause to be the same mac address showing up, but in a different vlan. Once we removed the DR vlan from the 6500 all was well. It seems like switches are ignoring the VLAN in the mac address table, and forwarding to the incorrect ports. The switch is not reporting any mac flapping in the logs. No spanning tree topology changes are occurring. Code version is 12.2(33)SXJ2 on all switches.
View 1 Replies View RelatedI have a new 881 router and am simply trying to change the ip address from the default 10.10.10.1 to 192.168.15.1
I tried doing this both in the CCP Express app loaded on the router, and also using the desktop CCP client. I can change other parameters without any problems, but when I change the ip address of the vlan the program hangs (as expected since the ip address should be changing). I then try to open it back up and reconnect but get no response from the router.
I can ping it no problem, and the http server is running according to the serial terminal.

But it never explains how to configure the stack IP address.

Recently purchased 5 SGE2010P 48-port switches to replace older L2 switches. I have 4 switches in single stack and one as a standalone. Both the stack and standalone will connect to at least 1 Dell 2724 switch. Both the stack and the standalone Cisco are in Layer 3 mode.
I have created several VLans on the Cisco switches, and am trying to assign an IP address to the VLan, but cannot seem to figure out the web gui. Each time I try to use Systems > System Management > IP Addressing > IP Interface, then click Add, it simply changes the existing IP of the management interface. So, I'm not sure how to go about assigning an IP Address to an Vlan.

View 3 Replies View RelatedI have a few old 2600 routers (2621, different IOS's) which I'm now replacing for new one's from the 2900 series (2901, Version 15.1(4)M4).In my configuration I have two IP addresses in my LAN interface and I have HSRP configured within the secondary IP subnet range. It would be something like this:
interface GigabitEthernet0/1
ip address 172.x.x.x x.x.x.x secondary
ip address 10.z.z.z z.z.z.z
[Code].....
Now, in the new 2900 routers, my interface configuration hasn't changed however I can see that the hello packets are now sent with the source within the respective HSRP IP subnet so I had to edit my acl for that:
permit udp 172.x.x.x x.x.x.x host 224.0.0.2 eq 1985
Is there a way I can force the HSRP to work as it previously did in the old IOS's?
