I have a icx7750 switch in a datacenter as routing device. Everything was running fine, but since we merge with a new organization, response time of the switch is very bad (ssh lag in cli) and we are now losing communication randomly with some servers behind. We added 4 access switch and 19 new router-interface ve (previously 2 switch and 49 interface ve).cpu and memory dont seems to be a problemcan a system parameters was not set correctly (see below)?thanksSSH@R0202000-DISTR-CT-RT-01#sh default valuessys log buffers:50 mac age time:300 sec telnet sessions:5ip arp age:10 min bootp relay max hops:4 ip ttl:64 hopsip addr per intf:24when multicast enabled :igmp group memb.:260 sec igmp query:125 sec hardware drop: enabledwhen ospf enabled :ospf dead:40 sec ospf hello:10 sec ospf retrans:5 secospf transit delay:1 secwhen bgp enabled :bgp local pref.:100 bgp keep alive:60 sec bgp hold:180 secbgp metric:10 bgp local as:1 bgp cluster id:0bgp ext. distance:20 bgp int. distance:200 bgp local distance:200System Parameters Default Maximum Current Configuredip-arp 8192 64000 8192 8192ip-static-arp 512 1024 512 512ip-cache 8192 32768 8192 8192ip-filter-port 2047 2047 2047 2047ip-filter-sys 3072 8192 8192 8192l3-vlan 32 1024 32 32ip-qos-session 1024 16000 1024 2048mac 32768 32768 32768 32768ip-route 98304 131072 98304 98304ip-static-route 64 2048 64 64vlan 64 4095 1024 1024spanning-tree 128 254 128 128mac-filter-port 32 256 32 32mac-filter-sys 64 512 64 64ip-subnet-port 24 128 24 24session-limit 65536 160000 65536 65536view 10 65535 10 10virtual-interface 255 512 255 255hw-ip-next-hop 17408 17408 17408 17408hw-traffic-condition 50 1024 50 50rmon-entries 2048 32768 2048 2048igmp-snoop-mcache 512 6144 512 512mld-snoop-mcache 512 6144 512 512ip6-route 5120 7168 5120 5120ip6-static-route 64 1024 64 64ip6-cache 1024 2048 1024 1024msdp-sa-cache 4096 8192 4096 4096gre-tunnels 16 64 16 16ip-vrf 128 128 128 128ip-route-default-vrf 65536 131072 8000 8000ip6-route-default-vr 2048 7168 2048 2048ip-route-vrf 4096 131072 4096 4000ip6-route-vrf 1024 7168 1024 1024pim-hw-mcache 1024 6144 1024 1024pim6-hw-mcache 512 2048 512 512igmp-snoop-group-add 4096 8192 4096 4096mld-snoop-group-addr 4096 8192 4096 4096mac-notification-buf 4000 16000 4000 4000openflow-flow-entrie 3072 3072 3072 3072openflow-pvlan-entri 40 40 40 40openflow-unprotected 40 40 40 40max-ecmp 8 32 8 8max-dhcp-snoop-entri 1024 3072 1024 1024max-static-inspect-a 512 1024 512 512
