thanks, how does it handle return traffic, does it follow the same pattern as mentioned in the document if so then for return traffic we need to create L3,L7 ACL ?

what if there is no match in L3 ACL , if traffic with port 513 and there is no matching L3 ACL rule so will it match the Default permit L3 rule and bypass L7 or it will go to L7 as no match in L3 Layer 3 Rules No match No match No match Does Default permit rule match ? Layer 7 Rules Matched - Traffic blocked Imp : what about reverse traffic because the ACLs we configure in MR are destination-based so return traffic will be allowed by default or denied ?

Hello Experts, In the L3/L7 ACL processing order, Does it match the 'Default permit any' rule in L3 ACL or just match the configured one? I have referred to the below document but could not see any L3 Rule which is no match but has an L7 match example source is 10.10.10.10 destination is 1.1.1.1 URL category is Email. there is no L3 ACL but there is L7 ACL which blocks the email category so the above packet will pass to the L7 or in L3 it will match Default any rule and bypass L7? and also what about return traffic, will that be allowed by default https://documentation.meraki.com/General_Administration/Cross-Platform_Content/Layer_3_and_7_Firewall_Processing_Order does reverse traffic also get evaluated in the L3/L7 ACL? -Pavan

Hello , How to clear stale client entries from the dashboard and how long they will stay on the dashboard, what is the timeout value for it? It creates a problem as I see duplicate IPs because the previously connected client IP address(192.168.100.50) still showing under clients and the new client has the same IP address. -Pavan

so the isolated ports can communicate to non-isolated ports and Isolated ports can not communicate to isolated port Is It the right understanding?

I took the captures Primart MAC - 14:9f:43:a3:ad:e8", Secondary mac- 14:9f:43:a4:09:88", VMAC": "88:15:44:38:00:01" so the calculation you mentioned does not match

As per the document, the first three octets would be 88:15:44, I want to know the calculation for the last three octets https://documentation.meraki.com/MS/Layer_3_Switching/MS_Warm_Spare_(VRRP)_Overview

Hello Experts, I have configured the warm spare between Meraki MS switches and it's working fine but I could not find the VMAC anywhere in the switch, I know it starts with 88-15-44 but wanted to know the full virtual MAC of the switch. I can find it by taking packet captures but want to know how Switch calculates it. Any RFC to refer for it? Regards, Pavan

This document says it starts with 88:15 but I want to find the VMAC of my switch. will there be the same Virtual Mac for all VLANs or will each VLAN have a separate VMAC?

Hello Experts, How do we find the virtual mac-address of the warm spare? How do we find the spare device IP address? or which address the spare device selects from L3 VLAN. example : Warm device has 10.10.10.1/24 then the next IP will be picked by spare 10.10.10.2/24 or any random IP will be picked? there will be the same Virtual mac for all VLANs or each VLAN will have a separate VMAC.

Hello , I have configured the ACL and want to confirm if it also get apply to traffic within VLAN: Confgi: VLAN 10 IP -192.168.10.0/24 ACL : "comment": "TEST_ACL2", "policy": "deny", "ipVersion": "ipv4", "protocol": "tcp", "srcCidr": "192.168.10.10/32", "srcPort": any, "dstCidr": "192.168.10.11/32", "dstPort": any, "vlan": 10 If I send a packet from 192.168.10.10 destined for 192.168.10.11 will it be blocked by ACL as this is local switching traffic? -Pavan

Hello Experts, I'm creating ACL on MS Switch and did not find an option to apply it anywhere. so does it get applied automatically to all interfaces in both directions of the switch and does it also get applied to all switches which are part of the network? -Pavan

The issue is resolved with the below config change : "portId": "1", "name": "FIXIA-P5-37", "tags": [], "enabled": true, "poeEnabled": true, "type": "trunk", "vlan": 101, "allowed vlans" 101 "portId": "3", "name": "FIXIA-P5-39", "tags": [], "enabled": true, "poeEnabled": true, "type": "trunk", "vlan": 201, "allowed vlans" 201

Hello Experts, I have created two L3 VLANs and each VLAN has one test PC connected, PC1 is not able to reach PC2. below is the setup: { "interfaceId": "3705899543372500746", "name": "NAME_VLAN_101", "subnet": "192.168.101.0/24", "interfaceIp": "192.168.101.1", "multicastRouting": "disabled", "vlanId": 101, "defaultGateway": "192.168.101.254", "ospfSettings": { "area": "ospfDisabled" } }, { "interfaceId": "3705899543372500747", "name": "NAME_VLAN_201", "subnet": "192.168.201.0/24", "interfaceIp": "192.168.201.1", "multicastRouting": "disabled", "vlanId": 201, "ospfSettings": { "area": "ospfDisabled" } } ] "portId": "1", "name": "FIXIA-P5-37", "tags": [], "enabled": true, "poeEnabled": true, "type": "access", "vlan": 101, "portId": "3", "name": "FIXIA-P5-39", "tags": [], "enabled": true, "poeEnabled": true, "type": "access", "vlan": 201, routing table : [ { "staticRouteId": "3705899543372501715", "name": "Default route", "subnet": "0.0.0.0/0", "nextHopIp": "192.168.101.254", "advertiseViaOspfEnabled": false, "preferOverOspfRoutesEnabled": false } ] Source - PC1(VLAN101) - 192.168.101.10 Destination - PC2(VLAN201) - 192.168.201.10 PC1 cannot ping PC2, In captures(taken on the dashboard for the switch) I can see the switch is sending an ARP request and receiving an ARP reply from PC2 but the ping fails. On the dashboard, the switch ARP table keeps loading and does not show anything. Note - The default gateway is not reachable as this is local switch routing. Do I need to toggle any settings for inter-vlan routing? Regards, Pavan
