Then configure RSM#2 to have an address in VLAN1 of 10.1.1.3/24. Then configure HSRP on both RSMs and use 10.1.1.1 as the standby IP. Mike W.

Re: HSRP design [7:28982]
If you want to load share the VLANs and provide resilience using HSRP both RSMs need to have an interface configured in every VLAN. Also I would not use VLAN 1 for data as this VLAN cannot be removed from a trunk and so propergates everywhere. RB.

Re: HSRP design [7:28982]
Mike, DMA channels are indeed the I/O's ports I refered to, but I couldn't remember what they were called (each time I learn something new , something old falls out the other end). I came across this about three years ago while setting up a multicast network and experiencing throughput problems, IOS was 112-13_P(1). It looks like Cisco have changed the allocation method, what IOS are you running? RB.

Re: HSRP design [7:28982]
Richard, Good information. Here is part of the output of this command when I give this command on one of our 5500 RSMs. FYI: We have 2 5500s with RSMs, however, with the exception of one VLAN, RSM#1 is the HSRP primary for all other VLANs. Heres the output: VlanTypeDMA Channel Method 1 ethernet1auto 2 ethernet0auto 8 ethernet1auto 142 ethernet0auto 200 ethernet1auto 201 ethernet0auto 202 ethernet1auto 203 ethernet0auto 204 ethernet1auto 205 ethernet0auto 206 ethernet1auto 1000ethernet0auto Is the DMA channel above the two I/O "ports" your spoke of? Just curious because you also mentioned that "By default all odd VLANs are assigned to the first port and all even VLANs to the second". AFAIK, we haven't changed the default behaviour on the RSM, and it seems to have split up the VLANs evenly across the two DMA Channels. What's your take on that? Mike W.

Re: HSRP design [7:28982]
The load balacing of the VLANs is recommended best practice, however the RSM does not have wire speed access to the backplane, it has two I/O "ports" each one 200Mbps FDX(from memory). By default all odd VLANs are assigned to the first port and all even VLANs to the second. So if you have all even VLANs supported on one switch, that RSM will only be using half of it's throughput capability. You can see the VLAN allocation by issuing the "show cont c5ip" command. After some initial queue stuff each VLAN is listed along with the "port" it is assigned to. To maximise the RSM capabilities you therfore have two choices 1. Split the odd and even VLANs over the two RSMs. 2. Reassign half of the VLANs in each RSM to the other I/O. This of course is only an issue of you are likely to exceed 200Mbps throughput. RB.

Re: HSRP design [7:28982]
I agree with Dave here. Make both RSMs part of every VLAN, then make RSM1 the HSRP primary for even VLANs, and RSM2 the HSRP primary for odd VLANs. Mike W.

RE: HSRP design [7:28982]
One thing need to be considered is what standby group you will configure for each vlan. Suggesting you to select different group numbers. e.g. interface Vlan5 ip address X.X.5.252 255.255.255.0 standby 5 timers 2 6 standby 5 priority 100 preempt standby 5 ip X.X.5.253 interface Vlan6 ip address X.X.6.252 255.255.255.0 standby 6 timers 2 6 standby 6 priority 100 preempt standby 6 ip X.X.6.253 Regards, Debra Chan -Original Message- From: khramov [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 12, 2001 5:23 PM To: [EMAIL PROTECTED] Subject: HSRP design [7:28982] Hello I have a design question.

Re: HSRP design [7:28982]
You make each RSM part of EVERY VLAN! Yes for redundancy and loadsharing even VLANS active for RSM1, odd for RSM2 is very reasonable and I think a recommneded way if you dig around CCO. I have done several of these with RSM's and MSFC in the 6500 series, works great.

RE: HSRP design [7:28982]
Are your distribution switches dual connected to the two 5505? Then you can do No. 3 and 4, but for efficiency you will need to make sure that the root bridge for those VLANs point to the right switch that is also doing the routing (the HSRP Primary) AG -Original Message- From: khramov [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 12, 2001 5:23 PM To: [EMAIL PROTECTED] Subject: HSRP design [7:28982] Hello I have a design question.
