Cisco IOS 12.4 Basic check to see if the command "ip nat pool" is available?We have 12.2 basic and I know it is in the 12.4 Advanced and 15.1 Basic versions (too large of a jump in version for management). Our budget is very limited so I am hoping that 12.4 Basic has this command.
View 2 RepliesI start configuring Cisco 2821 router for multicast . First short description and attached sheme explanation. Let we say I have small network with 100 users. One router and Cisco switch 3560. Two VLAN’s, one for data another for multicast. Data from internet works fine but now I want to connect multicast servers (or source of more multicast streams) from another subnet. Router have three interfaces.I expect there should be no problems with multicast configuration, but unfortunately it is not like I expect. What I did ?
First step: enable multicast routing
Second step: on both interfaces (Fe 0/1 and Fe 0/2) - ip pim sparse-mode
Third step: configure switch that users are connected to access port in VLAN 222 (temporary to see if multicast work)
When I start VLC on computer nothing happend. If I try to connect computer on same subnet where is source of multicast streams it works fine.What I am doing wrong ? Is there anything about routing ? All subnets are directly connected. RP is not needed if I have one router or ?

We currently have 7 Cisco 3524-XL switches (10-12+ yrs old) which are 10/100. We purchased a handful of Cisco 3750X switches to replace them going with the whole stackwise and redundant power supplies. Our current configuration on the old 3524 switches is that they have hardset all the ports on them to 100MB/FULL since devices would auto-neg to 100/Half. Since we're going from 10/100 to 10/100/1000 switches, I want things to auto-neg as I have heard in the past and experienced that things work better when it auto-neg to gigabit. My upper management is afraid since the old switches wouldn't auto-neg correctly that we should hard set all the ports on the new switches, which would be a nightmare since some ports would be hard set to 100/FULL others to 1000/FULL, etc.. We've tested just about all of our devices at auto with the switches and they've all auto-neg to the correct speed. In short, is Auto-Negotiation the way to go with the newer switches or is it still better practice to hard set your ports?
View 3 Replies View RelatedI am trying to configure the FE8 (WAN port) to connect to the Internet. We're swtiching ISP'ssoon so this router was set up at my office and has since been deployed at the client site. So far it is just plugged in and powered, with a console cable attached but no LAN cabling since this router will replace an existing one using the same addressing (except the WAN settings of course). So for now I am just focused on working on the WAN side since I have the ISP's cable modem attached . I had intiially used CP Express to config the wan port with an IP and mask and the various port forwarding options I intend to use. Now, connected via console cable, I tried pinging the IP of the wan port, which works. Beyond that, can't ping anyting (8.8.8.8 - a Google IP), also can't resovle any DNS names which makes sense with no apparent connectivity. Likely my config is just imcomplete. Nowhere in sh run do I see a Default Gateway, yet this ISP did specify one so I assume I need to enter it. Not sure what's the right way - I get confusing results on searches telling me either to use ip default-gateway or ip default-network. I want to think that it's as simple as entering in the IP but so far I've learned with the IOS that you never do anythign without knowing all the possible implications, which I don't. Also while I am at it, I don't know what I should have for DNS entries. This router will not be a DNS server for any internal systems that function will be managed by the two Windows 2008 R2 DNS machines. The ISP has also provided two IP's for their DNS servers. I thought it would be a simple matter of just adding two entrires via ip name-server command, which I did. So now I have four entries, first the two internal servers (inaccessible currently due to no LAN cabing to this router), and the two ISP servers. Can't ping those either, but again there's no default gateway.

First time user of cisco hardware and we just purchased the 4900m catalyst switch. My question is very general. I am simply hoping to network 3 servers together and I do not wish to do any fancy or advanced configuration. Can I simply use the web management interface for network administration and setup? I just downloaded the Catalyst 4500 Series Switch Cisco IOS software configuration guide and they talk about Cisco View network management system, is this my answer or is this what most people use for basic configuration and administration?

I' ve three 4900M switches equipped with the WS-X4920-GB-RJ45 module and the WS-X4908-10GE module. Now I'm started to setup these switches in our lab environment for the first time. They behave a little bit strange in comparison with the C3750 series which I used before and which I will replace by these powerful machines.
I tried to setup these switches to be managed through the management port. I configured IP address, default route in the management vrf, set the source-interface for tftp,ssh,ftp and tacacs to use the management port. Ping using the manangement port was successful. After finishing theses steps I configured the TACACS and AAA settings accordingly the informations I found on CCO. I tested the settings with "test aaa group authentication" command- without success. On my Cisco ACS no request was received and the switch told me he could't reach the tacacs server. Other switches in the same IP subnet are working without failure, so firewall or server should not be the problem.
I've got a Catalyst 3560G, and I want to reset the current index for a DHCP pool. I could remove the leases given for that pool, but I couldn't find this option.

In a stand alone 3750x switch configuration, can the secondary power supply only act as a redundant power supply (active/standby), or can it become a "pool" of power similar to power sharing mode for StackPower (somewhat active/active)? I understand there is no stack involved here but I'm curious if this functionality is possible.
View 1 Replies View RelatedThe last few days I've been exploring options in getting rid of some old routers accross a wan connections. I have a cat 3560 to play with and I thought I would try and use the no switchport command test out routing with switch. I've got some type of route issue and I tried a few things which I thought would fix the issue but had no effect. I'll post the config and a few commands so you can see what the basic setup is.
Here we can see in the arp that it knows about both 10.7.1.2 (PC unable to ping 10.3.3.254) as well as 10.3.3.254 (ASA).I tried adding in a ip route of 10.7.0.0 255.255.0.0 10.3.3.110 as well as 10.3.3.254. Neither produced the results I wanted allowing 10.7.1.2 (PC) to ping the ASA (10.3.3.254). [code]
We have two catalyst 3560 switches running c3560-ipbasek9-mz.122-58.SE2.bin They are connected using etherchannel using gi 0/21 - 24 interfaces.
on 3560-1 switch, there isn't any ip-default gateway or ip route configured. It only have 1 interface vlan configured.
on 3560-2 switch, there is ip default gateway configured along with 1 interface vlan.
What i dont understand here is that, i can reach out to other subnets from 3560-1 switch in which the routing is not enabled?
I used to "ip routing" command in order to enable inter-vlan routing, for example with 3750 cisco. I have a 6503 cisco with SUP720 MSFC3. I was able to create some vlans but I can not configure inter-vlan routing.

I created new VDCs. Since I have done so, there is not switchport command under the interface configuration.
The interesting this is that it is available on the admin VDC, but not the new VDC I created. I cannot create a peer VPC Peer link between my 2 Nexus switches. I did allocate ports to the new VDC and I did verify the enabled feature are the same.
why the switchport command is not available?

I just needed more insite into the function of the ip tcp adjust-mss command which can be used to adjust the MSS value in the tcp syn packet which passes that interface. But here is a question which I had. Consider that i have two sets of systems in my LAN one with an MTU value of 1300 ( MSS 1260 ) and with a MTU of 1500 ( MSS -1460 ). If I go ahead and put an ip tcp adjust-mss 1456 (for reducing the packet size from 1500 to 1496) on the WAN . Does the command only lower the MSS for the set of systems which have 1460 or will it also increase the MSS in the tcp syn packets send by systems with MSS of 1260 ( which can potentially break some communication ).
