I am trying to implement an etherchannel on a cisco 2901 (IOS 15.1). i have already created the port-channel but i cannot assign the gig interface to the channel group.
View 1 RepliesDoes the 2901 have etherchannel capabilities? If so, how to configure it? I mean, I can type "show etherchannel 1" in it, so I would assume if I can show it, I better be able to configure it, right?What about the 2911?
View 1 Replies View RelatedI have a 3560-48 switch running Cisco IOS Software, C3560 Software (C3560-ADVIPSERVICESK9-M), Version 12.2(44)SE3 and i need to implement basic QOS commands to the fast Ethernet interfaces as well as the gig interfaces and Also I need to create port channels on the switch and need what the port channel syntax are as well for that particular IOS version?
I have only read only access and i can't see what the QOS and Port channels syntax should be for that IOS version.
I'm trying to implement the UDLD protocol (Cisco-compatible), but face some problems. There is no enough information for implementing this protocol neither in RFC 5171 [URL] nor on [URL] How can I get a more detailed information regarding protocol state machines and timers?
View 2 Replies View RelatedI have attempted to implement DHCP snooping and have been having some strange issues. I have 5 3560s taht I use for my edge and when I attempt to implement on all five, the VLAN that houses my voice data appears to no longer be able to recieve DHCP lease renewals so after the 24 expiration all of my phones lose their configs. Once I roll back the changes the voice VLAN comes back. The other VLANs seem to function correctly as theya re able to renew their DHCP addresses.
The 3560s tie into each other using GIG Ports 1 & 2 and the top and bottom switches tie into our core switch, a 4507. The config that I use is below, failry simple and straightforward.
4 of the 5 switches feed our general office vlans for voice and data however the 5th switch is there for expansion and not in use. As such I have left the config changes in place on it and have tied myself and a colleague into it and have been operating fine for over a week now. So the config that I use seems sound in theory and should work on the other 4 switches with no issue.
I'm in the process of upgrading my 4507R core to a new 4507R-E. The old switch has Sup IV engines (WS-X4515) running IOS 12.2(40)SG and the new switch has Sup 6L-E engines running 15.1(2)SG. I'm trying to "move" my configuration from the old switch to the new. Below shows the commands configured in the old switch. I'm trying to determine how to implement the same configuration on the new switch since these commands are no longer available.
View 2 Replies View RelatedOur enviornment includes 3560 switches and 2800 routers. We have a few remote offices using an application on TCP port 1677 that use far to much bandwidth. Our WAN provider can throttle and police this for us, if I can TAG this traffic, for example all Traffic from Florida using the Groupwise app on TCP uses TCP port 1677 and I want it tagged with CoS 3.

some recommendations for product selection and overall infrastructure setup for our datacenter: We have an old, legacy setup, and are looking to replace equipment, improve performance, enhance security, and implement hardware redundancy (if cost effective).
1) We now have (2) IP blocks from our provider, and need to support both (because we have mailers on older IPs with a good reputation rating).
2) We have (2) aged Sonicwalls, one for each IP block, each connects to multiple internal subnets (some internal subnets need connectivity to eachother, some don't).
3) We have (mostly) public facing web servers (Linux/Apache), as well as database servers (with no external access).
Questions-
1) Should we implement a Cisco ASA 5520 w/ or w/o SSM modules for the new IP block (for webservers)?
1a) Should we implement a Cisco ASA 5510 or 5505 for the existing IP block (for mailers)?
1b) Or, can we have multiple public IP blocks connected to a single ASA 5520 (or 2 ASA's w/ failover)?
2) Can we connect both firewalls (5520 and 5510/5505) to a single Catalyst 3550 (or similar) using VLANs, and have 6 - 10 VLANs for webserver subnets, with ACLs controlling which subnets/servers can connect to eachother?
2a) Should we implement a second Catalyst 3550 (or similar) for redundancy (webservers have multiple network cards).
3) From our provider, we only have (1) dmark which both IP blocks connect through. Currently we have a switch connected to the dmark in order to 'splice' the connection, and have both existing firewalls connected. Is there a better approach to this?
4) We would like to implement SSL-VPN, and possibly site to site IPSec VPN, but only if there will not be significant performance degredation.
5) Other thoughts/recommendations for new features, enhanced security, or redundancy?

I have a problem with an etherchannel between a cisco 2950 and a couple of catalyst 4506. The cisco 2950 is connect via an etherchannel to the catalyst 4506A. The channel consist of two port on both side and is in trunk mode, encapsulation dot1q.Now i have the necessity to connect the 2950 to the other catalyst, 4506B. So, i copy the same configuration on the 4506B, but when I unplug the two rj45 cables from the catalyst 4506A to plug them in the 4506B the etherchannel doesn't go up in any way.

We have two 6k5 configured as vss and it is working fine. For each floor we have a 3750 stack. In each 3750 stack we have 4 switches. From the first 3750 we have a fiber link to the first 6k5 and from the fourth switch we have another fiber link to the other 6k5 switch, for each floor/3750 stack, both configured as etherchannel. We installled each 3750 stack/floor in different maintenance windows; in all these installations we have problems configuring the etherchannel. After we configure the etherchannel on 3750 stack and in the vss, the etherchannel does not go up/up. We see the etherchannel up/down; after a lot off work, try and error, configuring shut/ no shut, adding and excluding links from the etherchannel; in any aleatory moment the etherchannel goes up/up and works fine. Is there any bug related with these IOS versions, or is there any right procedure to configure etherchannel from vss to 3750 stack?

I am trying to review the port-channel configuration on a 6500 series. I am issuing the "show etherchannel summary" command and the out put shows the Group, Port-Channel, and Ports. It does not show me the protocol that is in use such as PAgP or LACP. Does this have to do with the Etherchannel in the "On" mode rather than "active", or "Auto"?
View 2 Replies View RelatedWe have a problem with the throughput over etherchannel in LACP with 2 or 4 ports. It is iSCSI traffic (vmware esxi 4.1 U3) is going from 2 separate NICs (ports) to the etherchannel (with 2 or 4 ports) that has a SAN connected (Nexenta).
The SAN is configured in passive LACP and the switch is in active LACP. Actually it does not matter if we do LACP or just MODE ON, still same result: ~1GBit/s throughtput in either direction. Like already mentioned, 2 or 4 ports in the etherchannel make no difference, or the configuration of the etherchannel.
I will post some config data below, but here is the question: Why can't we see traffic beyond 1GBit/s? Source and destination are capable of doing much more than that (vmware esxi RAID 5 of 1TB SATA; SAN 16 x 1TB NL-SAS). If we look with CNA, we can see that the traffic is balanced equally over the etherchannel ports. With or without QOS or flowcontrol, no difference. This whole traffic happenes on this switch.

The purpose of the etherchannel is to connect both switches to a private circuit provided by the hosted partner then route to the same setup in the DR location to different subnets.

View 3 Replies View RelatedI was configuring link aggregation between a Cisco3750 and Cisco SG200 and the switched network went down just a few minutes after the port channel came on.I rebooted the SG200 and all hosts came back up for a minute before I lost them again. The etherchannel was between two trunking ports. I never set link aggregation on the SG200, could that be the reason? All machines are connected to the SG200. The 3750 is only being used as a layer 3 device for inter vlan traffic.

View 1 Replies View RelatedWe have a new building where we added 3 network closets with 3750x stacks.We have 2 fiber gig ports connected to 2 microwave units and etherchanneled the to ports
We have the same setup at the corporate office except the connection is 2 fiber gig ports on a 6509. The 6509 is doing the routing
Now the problem is that we lost the connection to the management interface on only one of the three closets after a few days running. But some workstations at the corp office could reach it... others could not. The workstation were on the same VLAN. We solved the problem for a few days by shutting on of the fiber ports on the etherchannel. But is started happening again... now with PCs being installed at the new location.
The PC that was not working on the 3750x side could ping across to the 6509 but no further then that. It seems like an arp issue not routing because some devices are reachable and fully operational throughout the network.
